Oft-injured Kodai Senga likely returning to mound for Mets soon after setback

Kodai Senga could be back on the mound as soon as Thursday after a minor injury setback.

Mets manager Carlos Mendoza said Senga “felt good” after playing catch Tuesday, which is an encouraging update in the wake of his scratching from a minor league rehab assignment at Double-A Binghamton on Tuesday due to ulnar nerve irritation in his right arm.

“He was supposed to play catch [again] today, I haven’t heard anything,” Mendoza said before the Mets’ 9-2 loss to the Cardinals at Citi Field on Wednesday night. “We’ll see how he goes after he plays catch today. I wouldn’t be surprised if he’s pitching in a game tomorrow or the next day.”

The right-handed starter is in the midst of his recovery from lumbar spine inflammation.

Landing on the 15-day injured list April 28 (retroactive to April 27), Senga returned to New York and played catch off the mound before the Mets opened the series against the Cardinals.

He cited increased mechanical work and practice as the reasoning for his irritation, calling it “minor” and even straying away from labeling it as an injury.

“I got some treatment and the treatment effects were a little bit greater than I anticipated,” he said through a translator. “It became a little bit more loose, so that caused the nerve sensations. It’s not like it’s inflamed, I wouldn’t say this is an injury. Going back to what I said earlier, continuing to strive for those mechanics, striving for health and getting back to the field I don’t think is too far.”

The 33-year-old had made three rehab starts — one at Single-A St. Lucie and two at Triple-A Syracuse — before he was scratched. Over those three starts, Senga posted a 5.25 ERA and allowed at least two runs in each outing.

Not only did he walk or hit a batter in every appearance, but Senga was also unable to make it past the fourth inning in the first two starts.

RHP Jonathan Pintaro was recalled from Triple-A Syracuse, while RHP Joey Gerber was returned following Tuesday night’s game.

Pintaro pitched three innings, giving up one hit — a home run to Alec Burleson — while striking out two in Wednesday’s loss.

Mendoza said the changed starting pitching rotation of Austin Warren on Wednesday and Christian Scott on Thursday was nothing more than getting hurlers like Nolan McLean an extra day.

While Scott was initially slated to start Wednesday, Mendoza said the plan was “something that we discussed over the weekend.”

“It got out that Scotty was pitching today, but they knew the plan, the Cardinals knew the plan that we were going bullpen game today, Scotty tomorrow and then Noah,” Mendoza said. “Just kind of giving those guys an extra day this early on the stretch that we’re about to go here with 22, 23 days.

“We thought it was best coming off an off-day on Monday.”

Infielder Ronny Mauricio, who is currently on the injured list recovering from a fractured right thumb, has resumed baseball activities.

“He’s now on that phase where he’s doing a lot of the baseball stuff,” Mendoza said.
