Minor Monday: Mayo’s time to shine

Delmarva third baseman Coby Mayo had the opportunity to work out with Anthony Rizzo of the New York Yankees during the offseason.

They attended the same high school, Stoneman Douglas, in Parkland, Florida., so they already had a bond.

The program has produced another current major leaguer, Marlins left-hander Jesus Luzardo, and Rockies third base prospect Colton Welker.

Mayo hopes to follow in their footsteps.

“I didn’t get a chance to play with any of those guys, but I am super close with all of them.” Mayo said. “I worked out in the offseason with Rizzo. It’s great to pick his brain about this and be there every day with him.”

Mayo, 19, was selected by the Orioles in the fourth round of the 2020 Major League Baseball draft and signed for $1.75 million — above the $565,600 slot value. He slashed .455/.613/.772 with one double, two home runs, nine runs, and six RBIs in eight games during his senior season at Stoneman Douglas in 2020, which was shortened because of the Covid-19 pandemic.

Mayo earned his promotion to Low-A Delmarva after getting experience in extended spring training and the Florida Complex League for most of the summer. He slashed .329/.440/.566/.1.005 in 25 games with six doubles, four homers, five stolen bases and 15 RBIs.

“It’s been good over here,” Mayo said. “It’s a big change from living in South Florida. The schedule is a lot later than down there. I’m adapting to it. I’m having a great time, and I’m happy to be here. The play has been good. A little bit more fast-paced. The fans are great. I’m not used to having 2,000 fans there at a game but ,like I said, I’m adapting and it’s been a blast.”

Mayo is rated as the Orioles’ No. 14 prospect by MLBPipeline.com and No. 15 by Baseball America.


He’s adjusting to the pro game at third base. He has three hits, including a double and an RBI, in his first 17 at-bats for Delmarva.

“I think it’s just one step up from high school,” Mayo said. “I wouldn’t say it’s challenging, but it’s more fast-paced and you have to be more on your toes.”

Mayo has shown power at every step. He could be a force in the middle of the Orioles one day. MLBPipeline.com grades his power as 60, and he ranked near the top of their exit velocity readings during the 2020 instructional camp.

“I feel like I am doing a really good job in the weight room keeping myself strong,” Mayo said. “I am feeling really good at the plate … [The coaches] are very player-friendly and they know a lot about the game. I think everyone respects each other and that’s the best thing about it. Being in South Florida with these guys and then coming up here and being with them again has been really fun.”

Mayo has long-term goals, but he is focused on helping Delmarva reach the playoffs.

“We’re in the last stage of a playoff push and if we can grind together some wins, hopefully, we’ll get enough wins to get to a playoff spot,” Mayo said.

The Shorebirds promoted 12 other recent draft picks and signings to their roster, including Colton Cowser, the Orioles’ first-round pick.

Cowser was selected fifth overall out of Sam Houston State, where he slashed .374/.490/.680 with 16 home runs and 52 RBIs in 55 games this past season. Cowser began his professional career with the Florida Complex Leauge Orioles Orange, going 11-for-22 (.500) with a homer and eight RBIs.

Cowser managed a walk-off single in the 10th inning for a 5-4 win against the Fredericksburg Nationals on Saturday.

The other promotions include second baseman Connor Norby (2nd round), outfielders Reed Trimble (competitive balance round), John Rhodes (3rd) and Donta’ Williams (4th), right-handed pitcher Carlos Tavera (5th), infielder Collin Burns (6th), catcher Connor Pavolony (7th), infielders Billy Cook (10th), and Jacob Teter (13th round), right-handers Peter Van Loon (16th) and Conor Grady (18th ) as well as undrafted free agents Daniel Federman and Preston Price, both right-handed pitches.

Five are slotted into the Orioles Top-30 Prospects per Baseball America — Cowser (5th), Norby (10th), Mayo (15th), Trimble (20th), and Rhodes (26th).

Jannis has a solid debut: Knuckleballer Mickey Jannis was stellar in his first start with the Bowie Baysox, throwing six innings and allowing just one run on five hits with two walks and two strikeouts in the 5-3 win over the Reading Fightin Phils in 10 innings on Friday. First baseman Andrew Daschbach had two homers.

Jannis allowed seven runs on eight hits in his only appearance for the Orioles on June 23rd.

Ron Johnson honored: Longtime Norfolk Tides manager Ron Johnson will be inducted into the Tidewater Baseball Shrine at Harbor Park in between games of Norfolk’s scheduled doubleheader against the Charlotte Knights on  September 1st. Johnson managed the Tides during the final seven seasons of his career from 2012-18 and amassed 491 wins, making him the winningest and longest-tenured manager in franchise history.  The Tidewater Baseball Shrine recognizes players and executives who have significantly contributed to the game of baseball in the Tidewater area. Johnson died on January 26th at 64 of  Covid-19.

    Mayo and Henderson are the rare exception for Elias. He seems to like the college bats due to there ability to most likely move quicker than a high schooler. Henderson is already at a level higher than most kids his age. He’s obviously struggled a bit at Aberdeen but he’s been better outside of the 0-33 to start there. Mayo seems like mountcastle a guy that should move quickly if he’s able to tap into the raw power more. There was an article in the Baltimore sun about that yesterday.

      When did Mountcastle ever ‘move quickly’? I have him at 5 years in the minor leagues. Even after an MVP season at AAA, Elias was slow/hesitant to bring him up.

        Because he needed to work on his plate discipline. For a high school hitter five years is actually not bad. And Elias was right with mountcastle. With the exception of earlier this year he’s been much more patient and willing to take the walk.

          You are correct, O20. Mountcastle’s “plate discipline” has improved this year at the major league level. He could have come up two years ago and would now be much more advanced. As numerous examples on our minor league shuttle have shown, major league pitching and minor league pitching are quite different (O’s excepted, of course). You get better playing the best. Mountcastle is getting more walks because he’s the only one in the lineup worth pitching around. Another excuse for keeping him down was to teach him left field so that he could play first base. ME & Co. are just lucky that the kid has a great disposition and hasn’t been frustrated by all the senseless jerking around. And they’re still jerking him up and down the batting order. Has anyone read or heard ME say that he thinks Mounty will be part of a successful O’s team?

      Mayo hopefully won’t be compared to Mountcastle aside from the bat.

        If he hustles like Mountcastle, I’ll be happy with that similarity.

    It would be great to see Delmarva make the post season and get these young guys that experience. Instill a culture of winning through out the organization.

      Excellent point Bman! There is a helluva lot to be said about getting used to winning.
