BALTIMORE—Matt Harvey hasn’t won a game since May 1st and, in the 12 starts since then, he has completed five innings just once.

Harvey is the most experienced starter in a rotation that also includes Keegan Akin, Thomas Eshelman, Jorge López and Spenser Watkins. For now, he’ll remain in that rotation.

On Wednesday night, Harvey made his final start before the All-Star break. It was another tough one as the Toronto Blue Jays touched him for nine hits in 3 2/3 innings in a 10-2 Orioles loss before an announced crowd of 7,457 at Oriole Park.

Harvey’s night began with some controversy. Marcus Semien walked, and Bo Bichette singled him to second. Vladimir Guerrero Jr. lined to left, and Ryan McKenna tried to make a diving catch. The Orioles thought Semien was out at second when he didn’t get back to the base in time.

Instead, after a replay review, Guerrero was awarded a single and an RBI, and Semien was allowed to score.

Randal Grichuk’s force play scored Bichette, and Cavan Biggio’s double scored Guerrero. The Orioles were quickly down, 3-0.

Manager Brandon Hyde thought the Orioles should have turned a double play on Grichuk’s grounder.

“We don’t play our best defense behind him [Harvey], and that tends to hurt,” Hyde said. “I think it was a tough night, but there’s a long first inning. I thought we gave away a couple of outs to get him out of that first inning, to only allow one run.”

In the fourth, Harvey (3-10) gave up three more runs on RBI singles by Lourdes Gurriel, Bichette and Guerrero. In 3 2/3 innings, he allowed six runs on nine hits. His ERA is 7.70.

“They just kind of singled me to death,” Harvey said. “It was one of those starts where I left the ball over the middle a little bit, and they put the ball in play, and it happened to be where we weren’t playing.

“Obviously, frustrated. It’s been a rough first half. I’ve just got to hit the reset button. I think the break is going to help. I think a lot of us are banged up and tired and definitely need the rest and time off.”

Harvey won three straight games at one point, but since then he’s 0-9 with three no-decisions.

“It’s been good at times, and it’s been really bad at times,” Harvey said. “Really finding out what’s been causing those bad times, bad innings. It’s like, I go out, I have two, three good innings, four good innings, and then things pretty much all year have imploded.

“That’s something I’ll work for in the second half, try to just be more consistent throughout each start. With that time off, you can really look at what’s causing those last few things, whether it’s being a little tired or just get off your game plan a little bit. You’ve got to keep pushing through and figure out how to minimize the damage of bad innings.”

Hyde doesn’t have options with starting pitchers John Means and Bruce Zimmermann on the 10-day injured list. Means is expected back after the All-Star break. Zimmermann might not be back until the end of the month.

“Matt’s grinding right now,” Hyde said. “He didn’t pitch much last year at all. He’s going to get some time off to recharge. I think that’s important that he gets some time to rest because he’s really toed the rubber for us this entire first half. There’s probably some fatigue in there as well.”

Biggio’s sacrifice fly scored Teoscar Hernández with Adam Plutko pitching in the fifth.

The Orioles (28-58) scored a run against Hyun Jin Ryun (8-5) in the fifth. Domingo Leyba, Austin Wynns and Cedric Mullins began the inning with singles. Leyba scored on Austin Hays’ fly to deep center, but Wynns was thrown out at the plate to end the inning when he tried to score on Trey Mancini’s fly to right.

Ryu beat the Orioles for the third time since June 20th. In those three starts, Toronto (44-40) has scored 26 runs.

César Valdez gve up a two-run home run to Bichette, his 16^th, in the top of the sixth to make it 9-1.

Zac Lowther allowed a run on an RBI double by Hernández in the eighth. In the bottom of the eighth, Ryan Mountcastle’s RBI single scored Hays.

Kelvin Gutierrez, who was called up by the Orioles before the game after Maikel Franco was placed on the 10-day injured list, became the 46^th player used by the team this season when he played the ninth inning at third base. He walked in his only at-bat.
