BALTIMORE—When the parade of Orioles relievers came to the mound to try to hold off the aggressive Toronto Blue Jays hitters on Wednesday night, it became obvious that Hunter Harvey wasn’t going to pitch.

Harvey didn’t pitch in Tuesday’s game, either, and manager Brandon Hyde dismissed questions before the game, saying that Harvey was fine and available to pitch.

He wasn’t, and after the Orioles lost a painful 11-10 game to the Toronto Blue Jays, Hyde began his postgame media session by announcing that Harvey wouldn’t pitch again in 2019.

“Hunter Harvey, we’re going to shut down for the rest of the year,” Hyde said.

“Decided that before the game. We felt like he’s thrown enough innings this year and just quite rebounding from a little bit of soreness he had. We figure we get him ready for next spring training. Really happy with the year he’s had and want to end it healthy. Hunter is going to be with us but I won’t pitch him the rest of the year.”

Harvey pitched 6 1/3 innings for the Orioles since he was recalled from Triple-A Norfolk on August 17, striking out 11 and hitting 100 mph on the radar gun. He was shut down for 11 days this month because of biceps soreness. He threw a scoreless inning on Friday in Detroit in what will be his final action of the season.

“We just feel like he’s thrown enough,” Hyde said. “We’re really happy with the year he’s had. Want him to take the offseason and get ready for spring training.”

Overall, Harvey threw 82 innings with Norfolk, Bowie and the Orioles, the most he threw since 2014 when he pitched 87 2/3 with Delmarva.

“Didn’t feel like it was necessary to have him pitch anymore,” Hyde said. “He’s thrown more this year than in a long. long time and never thrown this late in the year. We just want to keep him healthy.”

Painful loss: In a season full of meltdowns and improbable losses, this was perhaps the most incredible.

Leading 7-1 early in the game and holding a 9-5 lead entering the ninth inning, Miguel Castro imploded, giving up six runs and a grand slam in the 11-10 loss.

After striking out Teoscar Hernandez to begin the inning, Castro walked Rowdy Tellez. Richard Urena singled and Billy McKinney walked, the ninth walked issued by Oriole pitchers

Bo Bichette struck out and Cavan Biggio singled for a run. Randal Grichuk, who terrorizes the Orioles, hit a grand slam on a 3-1 pitch, and the Orioles trailed, 10-9.

Vladimir Guerrero Jr. reached on a two-base error by shortstop Richie Martin and scored on Reese McGuire’s RBI single.

“There are good days and bad days,” Castro said through a translator. “Unfortunately, today was a bad day for me. I think it was just a pitch that cost me the game.”

The Orioles had a chance to win it in the bottom of the ninth but scored just one run and left the bases loaded.

Austin Hays led off with a single against Derek Law. Mark Trumbo walked and, with one out, DJ Stewart doubled to right, scoring Hays. Pinch-runner Hanser Alberto stopped at third.

Stevie Wilkerson walked to load the bases, but Law retired Jonathan Villar on a fly to left and Trey Mancini on a grounder to second.

“The right two guys up,” Hyde said. “It didn’t happen. I love having those two guys up in that situation and both have been swinging the bat really well, but we just didn’t score there.”

Bundy’s night: Dylan Bundy huffed and puffed his way through five innings in his final home start of the season. Bundy, who had won just one of his previous nine starts, equaled a career high with five walks. He struck out eight.

“Weird. It was a weird outing,” Bundy said. “Just no command, really, the first three innings. Just missing a little bit off, missing a little bit over the plate and they’d foul it off. Just wasn’t quite able to get those pitches that I needed to get the guys out earlier in the count and prolonged the at-bat.”

Bundy escaped from a bases-loaded jam in the first, in which he walked two. In the second inning, he walked two more, and gave up his only run on Bichette’s RBI single.

The Orioles scored two runs on three straight doubles in the first against a one-time nemesis, Clay Buchholz. Anthony Santander, Rio Ruiz and Hays each doubled.

Mancini continued his hot hitting with a two-run double in the second to give the Orioles a 4-1 lead.

Villar, who hit a long drive to left that appeared headed out of the park before Derek Fisher leaped over the fence to snag it, hit a one-out homer in the fourth, his 23^rd home run. After Mancini singled, Santander hit a long home run to right, his 19^th, and the Orioles led, 7-1, driving Buchholz from the game.

Tanner Scott allowed a run in the top of the sixth on Bichette’s RBI single.

Hernandez hit a three-run home run against Shawn Armstrong in the seventh to cut the Orioles lead to 7-5.

Ryan Eades got two outs but walked McKinney and gave up a single to Bichette before Paul Fry retired Biggio on a fly to center, ending the seventh.

Stewart’s sacrifice fly to right gave the Orioles an 8-5 lead in the seventh.

Mychal Givens worked a 1-2-3 eighth, the only one by Oriole pitching.

“I love the way we were playing early,” Hyde said. “I thought we swung the bat great. We were running the bases well early. Dylan Bundy had a couple of tough innings early, but bounced back to give us five good innings and left with a nice lead. Grinded through that fifth inning.

“Tanner Scott came out of the bullpen and was throwing strikes. I’ll take that any day of the week, throwing 97 with good sliders, got hit a little bit. I think that’s a positive, coming in and throwing strikes there. Army had a tough time. Eades was OK. Fry did a nice job getting a left-hander out, Givens faced the middle of the order, and we have a four-run lead in the ninth and can’t get it done.”
