Dean Jones Report: Updating our Orioles’ prospect rankings

The 2019 season unofficially begins Saturday morning.

That’s when the Orioles will welcome thousands of fans to the Baltimore Convention Center for their annual FanFest. If you’re a season-ticket holder, you can get in at 10 a.m. Everyone else needs to wait until 11 a.m., but the festivities will last throughout the day.

After the weekend, we’ll look ahead to spring training. It starts in just over two weeks. Pitchers and catchers report Feb. 12 and the full squad on Feb. 17.

It’s the beginning of a new era in Birdland.

As we all know, the Orioles endured a brutal 2018 season. They finished in last place in the American League East Division for the second straight year, posting a 47-115 record.

That led to the departures of executive vice president Dan Duquette and manager Buck Showalter. In their places, the Orioles hired Mike Elias and Brandon Hyde, respectively.

While Elias and Hyde have started to mold the organization the way they would like to – including hiring analytics guru Sig Mejdal as assistant general manager – the Orioles still have a lot of work to do on many fronts. A successful turnaround won’t happen overnight.

Of course, the Orioles’ minor leagues will play a critical role in the success of the rebuild.

With low expectations for the major-league squad this season, fans will focus on what’s happening with the club’s top prospects. It’s the same thing that happened a decade ago.


In the “dark years” before the Orioles surprised the baseball world with a wild-card berth in 2012, everyone wanted to know how catcher Matt Wieters, shortstop Manny Machado, left-hander Brian Matusz, and others were playing. The major-league club took a backseat.

With my annual “Dean’s Dozen” rankings of the Orioles’ top prospects – and the “Dean Jones Report” updates throughout the season – I hope to give a bit of guidance on some of the players who could factor into the club’s rebuilding efforts in the coming years. And as always, I’d love to hear your thoughts. Share your comments at the bottom of the post.

Also, I plan to re-evaluate my rankings before the minor-league season kicks off in early April. If any of the players make the Orioles’ Opening Day roster – or if any other minor leaguers step up heading into the season – I’ll have to find a spot for them on the list.

One final note: Baseball America released its annual Top 100 prospects list this week. The Orioles have three representatives – outfielder Yusniel Diaz (No. 37), left-hander DL Hall (No. 54), and infielder Ryan Mountcastle (No. 90). As you’ll see below, those three players are atop my initial list, too. But notice that they’re in a different order – for now, at least.

Meanwhile, is set to unveil its Top 100 rankings this weekend. I believe it’s scheduled to take place during a broadcast on MLB Network at 8 p.m. Saturday.

With all of that out of the way, let’s get to the updated Dean’s Dozen rankings…

No. 1: Ryan Mountcastle, 3B
2018 Statistics: .297, 13 HRs, 59 RBIs, 19 2Bs, 4 3Bs, 63 runs in 102 games (Double-A Bowie) Player Page

A year ago, I ranked the 2015 first-round pick (36th overall) at No. 2 in my preliminary 2018 rankings – behind outfielder Austin Hays. As Hays struggled, Mountcastle – who will turn 22 on Feb. 18 – eventually rose to the top spot. But right now, the same thing I said about Mountcastle before the 2018 season is still true: The biggest uncertainty remains what position he’ll play over the long term. I’m curious to see if Elias and his new hires make any changes on that front before this season begins – or as it plays out. For now, Mountcastle is at the top of my rankings after another solid offensive year at Bowie. He’ll likely start the upcoming season with Triple-A Norfolk. From there, we’ll see what happens.

No. 2: Yusniel Diaz, OF
2018 Statistics: .314, 6 HRs, 30 RBIs, 10 2Bs, 4 3Bs, 36 runs in 59 games (Double-A Tulsa); .239, 5 HRs, 15 RBIs, 5 2Bs, 23 runs in 38 games (Bowie) Player Page

Overall, the Cuba native failed to live up to the initial hype during his short stint with the Baysox in 2018. Diaz, 22, only batted .239 in 38 games after joining the club in mid-July from the Los Angeles Dodgers’ organization – including just .188 in 23 games at Prince George’s Stadium in Bowie. While those struggles are a little concerning, you must realize that it’s a small sample size. Before he was acquired in the deal that sent Machado to the Dodgers, Diaz hit much better at Double-A Tulsa (.314 in 59 games). And he showed the ability to perform on the big stage, hitting two homers in the All-Star Futures Game at Nationals Park on July 15. Both Baseball America and list Diaz as the Orioles’ top prospect, but I’m going to slot him in just behind Mountcastle to begin the year. He’ll likely start the season at Norfolk. If all goes well, he’ll be playing at Camden Yards soon enough.

No. 3: DL Hall, LHP
2018 Statistics: 2-7, 2.10 ERA, 100 Ks, 42 BBs in 94 1/3 innings (Low-A Delmarva) Player Page

While looking back at our Orioles’ Minor League All-Star Squad from last fall, I realized I could have easily picked the 2017 first-round pick (21st overall) – or even left-hander Zac Lowther – instead of selecting left-hander Keegan Akin. Hall, 20, went 2-2 with an incredible 0.84 ERA in 11 games (10 starts) after the South Atlantic League All-Star break. He struck out 64 hitters and only gave up 32 hits in 53 2/3 innings over that span. In other words, he had two strikeouts for every hit allowed in the second half. We’ll see if Hall can carry the momentum into 2019. He’ll start the season in Frederick’s rotation.

No. 4: Austin Hays, OF
2018 Statistics: .242, 12 HRs, 43 RBIs, 12 2Bs, 2 3Bs, 34 runs in 66 games (Bowie); .189, 0 HRs, 3 RBIs, 6 runs in 9 games (Short-A Aberdeen) Player Page

For now, we’ll call it a lost season for the 2016 third-round selection. Hays, 23, earned the Orioles’ Brooks Robinson Minor League Player of the Year award in 2017 after batting .329 with 32 homers, 95 RBIs, and 32 doubles in 128 games between Frederick and Bowie. And as you’ll recall, he finished that season with 20 games in the majors. But last year, Hays stumbled out of the gate. Through the first two months, he batted .224 with 43 strikeouts and only 18 RBIs in 43 games. Then, he missed more than two months because of an ankle injury before returning in early August. The Orioles initially selected Hays for the Arizona Fall League, but he didn’t play because of lingering soreness in his ankle. Finally, in mid-September, Hays underwent surgery to repair a stress fracture. He’s expected to make a full recovery, but it’s a situation worth monitoring during spring training. At best, he’ll be on the Orioles’ Opening Day roster. At worst, he’ll begin the year in the Tides’ outfield.

No. 5: Keegan Akin, LHP
2018 Statistics: 14-7, 3.27 ERA, 142 Ks, 58 BBs in 137 2/3 innings (Bowie) Player Page

The 2016 second-round pick collected a lot of awards in 2018. The Eastern League selected Akin, who will turn 24 on April 1, as its Pitcher of the Year. The Orioles honored Akin and Lowther as co-winners of the organization’s Jim Palmer Minor League Pitcher of the Year award. And perhaps most important, as I mentioned earlier, he earned the “starting pitcher” spot on’s third-annual Minor League All-Star Squad. I’m joking, of course. But Akin truly dominated Double-A last season, leading the Eastern League in wins (14) and strikeouts (142). His 14 wins were just one shy of right-hander Brad Bergesen’s franchise record in 2008. With the Orioles under new management, I’m curious to see what happens with Akin. I would think that he will get a chance to make the major-league team out of spring training. And if nothing else, he should be pitching for the Orioles this summer.

No. 6: Grayson Rodriguez, RHP
2018 Statistics: 0-2, 1.40 ERA, 20 Ks, 7 BBs in 19 1/3 innings (Rookie-Level Gulf Coast League Orioles) Player Page

Rodriguez, 19, surrendered five runs – two earned – and five hits in 1 1/3 innings as the GCL Orioles fell, 10-4, to the GCL Red Sox on Aug. 9. If you take out that start, the 2018 first-round selection (11th overall) would’ve finished with a miniscule 0.50 ERA in 18 innings during his first professional season. Nevertheless, he still posted a 1.40 ERA in 19 1/3 innings. Rodriguez struck out 20 batters and only allowed 17 hits. If I were running the show, I’d be aggressive and move Rodriguez up to Delmarva this year. It’ll be at least a few years before he pitches at Camden Yards.

No. 7: Zac Lowther, LHP
2018 Statistics: 3-1, 1.16 ERA, 51 Ks, 9 BBs in 31 innings (Delmarva); 5-3, 2.53 ERA, 100 Ks, 26 BBs in 92 2/3 innings (High-A Frederick) Player Page

Among qualifying pitchers in the Orioles’ minor-league system last season, the 2017 competitive balance round B pick finished first in strikeouts (151) and ERA (2.18). And Lowther, who will turn 23 on April 30, only walked 35 hitters in 123 2/3 innings between Delmarva and Frederick. If you’ve read my updates over the past couple of years, you know I’m more optimistic on Lowther’s future than most others who cover the Orioles’ prospects. But I think we’re all in agreement on one thing: This will be a critical year for Lowther. As he moves into the upper levels – almost certainly beginning at Bowie on Opening Day – we’ll see if he can continue to shine or if more experienced hitters will get the best of him.

No. 8: Dean Kremer, RHP
2018 Statistics: 5-3, 3.30 ERA, 114 Ks, 26 BBs in 79 innings (High-A Rancho Cucamonga); 1-0, 0.00 ERA, 11 Ks, 3 BBs in 7 innings (Double-A Tulsa); 4-2, 2.58 ERA, 53 Ks, 17 BBs in 45 1/3 innings (Bowie) Player Page

Kremer, 23, pitched well in eight starts last season after coming over to the Orioles from the Los Angeles Dodgers in the deal for Machado. The Dodgers’ 2016 14th-round selection went 4-2 with a 2.58 ERA and 53 strikeouts in 45 1/3 innings. Overall, Kremer struck out 178 hitters – which led all minor leaguers in 2018 – in 131 1/3 innings while splitting the season between the High-A and Double-A levels. We’ll probably see Kremer at Norfolk to begin the year. If he continues to excel, a major-league call-up could come this summer.

No. 9: Ryan McKenna, OF
2018 Statistics: .377, 8 HRs, 37 RBIs, 18 2Bs, 2 3Bs, 60 runs in 67 games (Frederick); .239, 3 HRs, 16 RBIs, 8 2Bs, 2 3Bs, 35 runs in 60 games (Bowie) Player Page

Let’s never forget that the 2015 fourth-round pick batted .377 in 67 games for Frederick at the start of the 2018 season – including .397 in 28 games in May and .423 in 16 games in June before moving up to Bowie. But McKenna, who will turn 22 on Valentine’s Day, experienced some growing pains with the Baysox. In 60 games, he only hit .239. His on-base percentage dipped from an amazing .467 with the Keys to .341 in Double-A. With that said, it isn’t time to quit on McKenna. He’ll likely get another crack at Bowie to begin the year. An aggressive track could see him in the major leagues by sometime in 2020.

No. 10: Blaine Knight, RHP
2018 Statistics: 0-1, 2.61 ERA, 8 Ks, 3 BBs in 10 1/3 innings (Aberdeen) Player Page

Last summer, the Orioles only saw the 2018 third-round selection pitch four games within their organization. That’s because Knight, 22, didn’t sign until early July after leading Arkansas into the College World Series best-of-three finals against Oregon State – which, coincidentally, featured the Orioles’ 2018 competitive balance round A pick Cadyn Grenier. With Aberdeen, Knight went 0-1 with a 2.61 ERA in 10 1/3 innings. The Orioles will probably take a conservative approach and put Knight at Delmarva to start the 2019 season. However, with significant college experience, he could quickly move to Frederick if he does well – similar to what Lowther and right-hander Michael Baumann did in 2018.

No. 11: Dillon Tate, RHP
2018 Statistics: 5-2, 3.38 ERA, 75 Ks, 25 BBs in 82 2/3 innings (Double-A Trenton); 2-3, 5.75 ERA, 21 Ks, 9 BBs in 40 2/3 innings (Bowie) Player Page

Reportedly the cornerstone of the trade that sent closer Zach Britton to the New York Yankees last July, the Texas Rangers’ 2015 first-round pick (fourth overall) underwhelmed in seven starts with Bowie in 2018. Tate, who will turn 25 on May 1, went 2-3 with a 5.75 ERA. Opponents hit .302 in 40 2/3 innings against him with the Baysox. The Orioles added Tate to their 40-man roster in the fall to protect him from the Rule 5 draft in December. But with so many other young pitching prospects in the system now, he needs to bounce back in 2019 if he wants to remain in the club’s future plans. With a strong showing in the spring, Tate could enter the discussion for a rotation spot. However, he’ll likely begin in Norfolk.

No. 12: Cadyn Grenier, SS
2018 Statistics: .216, 1 HR, 13 RBIs, 12 2Bs, 2 3Bs, 23 runs in 43 games (Delmarva) Player Page

I considered putting many other players in my preliminary Top 12 rankings – including Baumann, right-hander Brenan Hanifee, and third baseman Jean Carlos Encarnacion. But ultimately, I decided to go with Grenier, 22, in the final spot. After initially struggling offensively in his first professional season, Grenier rallied to finish with a .216 average in 43 games for the Shorebirds. He was hitting a season-low .163 on Aug. 11 before going 19-for-64 (.297) with 11 runs in his final 16 games. Better known for his defense, Grenier will need to hit a little bit in order to keep advancing through the organization. He’s still at least a couple of years away from the majors, but we’ll probably see him in Frederick in 2019.

    Good Friday to you Dean. Love, love, lover your reports, so it’s super to see you back!

    And since when has your list dominated by pitching prospects? I don’t ever remember that ever being the case. I certainly hope you’re not just teasing us. ‘Cause IMHO … pitching is where it all starts.

    I got to watch Dillon Tate a few times at Bowie last year, when his control is on and he can keep the ball low in the zone he does pretty well. As the game goes on and either he tires and the ball comes up or its the third time through the lineup he wasn’t fooling anyone. See him being moved to a setup role in the near future.

    Ryan Mountcastle can rack, I think his bat plays in the majors now, his glove is another story. Not sure where he plays but don’t think third is the position for him.

    My sleeper for O’s minors this year is Ryan Bannon, he didn’t hit well last year but liked the way he fielded. I think his bat will recover and he advances to AAA this year.

    Just a fans opinion

    Great report. I agree Ryan Mountcastle is number one. Kid can hit and when you can hit they eventually find a position for you to play. I’d say 1st base, but the $161,000,000 man has that covered for the next four years. I’m not sure I agree with Austin Hays at 4th on the list however. As you mentioned he was hurt last year. I wouldn’t be surprised to see him on the opening day roster and DJ Steward starting the season at Norfolk.

    Dean, pleas add defense to your reports this year. I realize that you have mostly pitchers on the list know but for those position players a complete picture of their play is helpful. Box scores really don’t tell us much about a player’s defense. Errors alone don’t mean a lot. Didn’t Jeter have something like 30 errors before being called up? We all know that Mountcastle can hit. What we don’t know is if he can handle any position in the field. He won’t help much if he is only a DH especially if Trumbo is on the 25. Does Grenier make all the plays he should be making? How are his throws? What is his range? Good defense was lacking last year. Hopefully this regime will put more of a priority on it.

      Completely agree. Defense is important. We already have a terrible leftfielder and two designated hitter/1st baseman types, it would be unfortunate If it turns out that we wasted a first round pick on yet another one.

    Dean: I will be an avid reader of your reports this year. The “talent pipeline” has to start in the minors and from what I read in your first of the year report, we aren’t in too bad a shape. I, personally like seeing 3 left handed pitchers in your top 7 prospects. That is really encouraging since we haven’t had a left starter on the major league club since Wade.

    Dean — Thanks for the report. It makes us feel that spring really is just around the corner. One question: might your estimates about when these prospects would reach the majors be a bit optimistic, since the club has a vested interest in not starting their service clocks too soon — especially since the team isn’t going anywhere this year anyway? Actually, two questions: might Ortiz vault ahead of Tate if he reports in decent shape?

    Good to see you back! I closely follow the top four O’s farm teams and look forward to your reports on the progress (hopefully) of their hopefuls. I’m a fan of Wells and since you didn’t include him I’m guessing it’s because of his inconsistency last year. The previous year, at Delmarva, his control was incredible but he wasn’t able to sustain it last year at Frederick. My take on him, though, is that he’s a pitcher, not a thrower, and uses his brain to get by without the “heat”. What’s your “take” on him?

    As far as Grenier is concerned, I read all the “hype” on him after the draft about his defensive skills. WOW, was that ever wrong! I saw two games and, to me, he looked somewhat lost in making decisions with what to do with the ball when he got it. I saw two infield singles because he doubled (triple) clutched before throwing the ball to first. If he can’t hit and his defense is suspect then why do we need him? We have a lot of defensive liabilities already on the roster.

    Dean you could very well become a celebrity of sorts as the Minor Leaguers take center stage in this rebuild. Diaz coming here and dropping off I’ll attribute to the curse of 2018. Hays–seems he never was the same after the 2017 call up.

  9. Pip

    January 25, 2019 at 10:59 am

    Enjoyed this article very much. Looking at our trade returns, it is surprising that so many competent prospects were drafted in the very lower rounds, which indicates that our own Scouting isn’t very good.

    I’ve only been following this site since early last season but the minor report has become one of my favorites.

    As you indicated, it’s going to be a down year for the major league team and that will make the progress of the minor league players more interesting. Looking forward to your work through the season.

    I’m new on this site, but a lifetime O’s fan. I went to the World Series in79 and 83, and a bunch of the playoffs. I’ve been a die hard fan since 66. I live between Myrtle Beach and Wilmington, NC allowing me to attend the Keys in MB, and new this year, Fayetteville, NC. I look forward to the Keys having a better year than the O’s, but that doesn’t lessen my love for the O’s! My question for you, “Who should I be keeping an eye on for the Keys?” Also, with us having a good [position in the draft, who do you think the O’s will draft? I hope Bundy does great this year, and finally becomes a staple on the list of solid ML Pitches. He’s a terrific guy. A few years ago, Bundy was playing in Myrtle Beach, starting the game. He was one of the players my son said was going to be great. After the game, Bundy took the time to call my son who was in the hospital recuperating from surgery. He actually spent a long time, talking to my son. He signed a ball, which he got out of his own equipment bag, and told me to give it to my son. At a time when pro athletes are viewed as money grubbing players, it was great to actually meet a player who was so genuine, and considerate. I’ll be a Bundy fan, as long as he continues to play! BTW, great information you have provided on here! I think despite the growing pains, the O’s will be competitive, and surprise a lot of people!
