An hour before Saturday’s game against the Marlins, the Mets made some roster moves, recalling right-hander Jordan Yamamoto from Triple-A Syracuse, putting left-hander Stephen Tarpley on the 40-man roster and designating infielder Jake Hager for assignment.

Both Yamamoto and Tarpley will work out of the bullpen. The Mets need help after using seven relievers in Friday’s 6-5 victory over Miami. Yamamoto was on the taxi squad as recently as Friday. He appeared in one game for New York and allowed one run in 2 2/3 innings.

Tarpley was on the COVID-19 injured list and appeared in one game for New York on April 24. It was against the Nationals and he didn’t retire a batter after facing four hitters.

In order to put Tarpley on the 40-man roster, the Mets had to let Hager go and it appeared to upset manager Luis Rojas. Hager, after all, collected his first big league hit on Friday.

“It was really tough. I can imagine it was tough for him,” Rojas said about Hager. “Watching him play like he did last night as a pinch-runner and later in the game getting that clutch hit up the middle, it’s tough. ... I told him this is something that could happen and not put his head down. He [was able to] get himself to [the big leagues]. He was one of our best hitters in Syracuse. [I told him to] keep working hard, look forward and I pray that he is with us and we meet up down the road.”

Injury report

Outfielder Brandon Nimmo, on the injured list because of a bone bruise in his left index finger, said he is close to swinging a bat, but he is not going on a rehab assignment anytime soon.

Nimmo doesn’t know when he will return to action. He wants to make sure that the nerves in the finger are 100 percent. He aggravated the nerve during a rehab assignment last week. It didn’t help that he was jammed on a pitch.

“I feel a lot better than I was a week ago,” Nimmo said. “I’m very optimistic the way things are heading right now.”

Second baseman José Peraza did not start in Saturday’s game because of a right leg contusion, but he is available against the Marlins. Peraza hurt his leg in the top of the fourth inning on Friday after he was hit by a pitch from Marlins right-hander Zach Pop.

Worth noting

Catcher Deivy Grullón has been claimed by the Rays and left-hander Daniel Zamora has been claimed by the Mariners.
