Velocity, command elude Chapman again in defeat

Aroldis Chapman was bad again in Wednesday’s 6-3 loss to the Blue Jays, giving up a monstrous homer to Vladimir Guerrero, Jr. to lead off the ninth inning at the Stadium.

The left-hander, who walked two of the four batters he faced after Guerrero and was removed for Wandy Peralta, has given up four runs in his past seven innings (over eight appearances) and has been struggling with his fastball. Chapman’s command issues aren’t going anywhere, either, as he has walked eight in that span.

His velocity was consistently in the mid-90s — a speed at which Chapman can’t get batters out consistently.

Manager Aaron Boone attributed Chapman’s issues to an inability to “sync up his mechanics consistently.”

➤ Gerrit Cole was “doing pretty well,” after leaving Tuesday’s loss with a tight left hamstring in the fourth inning, Boone said.

The right-hander underwent some testing Wednesday, and Boone said an MRI exam was still not scheduled, but hasn’t been ruled out.

Cole was able to do some work on a treadmill and Boone said the ace was “encouraged” by how he felt.

Still, it will be another day or two before the Yankees will know the severity of the injury, and whether Cole could miss his next start.

“I think the next 24-48 hours will determine where we move and how he responds,’’ Boone said.

After Tuesday’s game, Cole said it was “tough to say right now” whether he’d be able to make his next start.

“I’m obviously disappointed about the outcome,’’ Cole said. “I just want to reserve judgment and see how this thing reacts the next 24-36 hours.”

➤ Boone said Domingo German and Luis Severino made it through their bullpen sessions on Tuesday without any issues. Each of the right-handers is expected to throw another bullpen session, which Boone called “an encouraging step.”

German, according to Boone, is further along than Severino as both battle back from shoulder injuries.

Right-hander Michael King, out since July with a right middle finger contusion, threw three innings in relief at Triple-A Scranton/ Wilkes Barre on Tuesday, and Boone said he could join the Yankees’ staff soon.

➤ Aaron Judge reached on an infield hit in the seventh innning to snap an 0-for-22 skid. … Gio Urshela didn’t play, and Boone said it was a day off for the third baseman. He’s 1-for-8 with a pair of strikeouts in three games since returning from a left hand injury. Urshela also made two errors in Monday’s loss, but had no issues Tuesday. … Pitching coach Matt Blake was tossed for arguing balls and strikes from the dugout during Luke Voit’s at-bat in the bottom of the ninth. Voit struck out swinging.

➤ The slumping Joey Gallo, who was given Tuesday off, was back in the lineup. He went 1-for-2 with a run and a pair of walks.

“I felt good and was seeing the ball well,’’ Gallo said. “I’ve been seeing the ball well the whole time. I tried to put the ball in play a little bit more.”

He struck out once Wednesday after whiffing in all four plate appearances Monday.

➤ A brief “Der-ek Jet-er” chant erupted from the Bleacher Creatures during the roll call.

Many Yankees players watched Derek Jeter’s Hall of Fame speech on the outfield scoreboard screen before batting practice. Boone watched the speech, as well, and said he got to “witness another Hall of Famer I got to play alongside.”
