Michael Wacha and David Peterson are back, but the Mets encountered another pitching injury Friday, as they placed Corey Oswalt on the 10-day injured list with right biceps tendinitis.
Oswalt last pitched Tuesday, when he threw four scoreless innings in a loss to Miami.
Manager Luis Rojas said the right-hander began feeling discomfort Wednesday and did not throw. Oswalt received treatment, and after speaking with Rojas on Thursday, the roster move was made.
It was one of several made by the Mets prior to their doubleheader sweep of the Yankees.
To make room for Peterson, who started Game 2 against the Yankees, they designated Walker Lockett for assignment.
Andres Gimenez (undisclosed) and Jake Marisnick (left hamstring strain) were activated from the IL and Marisnick started in center field in Game 1 of the doubleheader in The Bronx.
To make room for Marisnick, the Mets designated Juan Lagares for assignment.
Additionally, the Mets recalled catcher Pat Mazeika as the team’s 29th man for the twin bill and also added infielder Brett Baty to the 60-man player pool and assigned him to their alternate site in Brooklyn. The 20-year-old Baty was the 12th-overall pick by the Mets in the 2019 draft. In 51 games last season between Brooklyn, Kingsport and the GCL Mets, Baty hit .234/.368/.452 with 37 runs, 16 doubles, two triples, seven home runs and 33 RBI.
The Mets also claimed outfielder Guillermo Heredia off waivers from the Pirates. Heredia was optioned to the team’s alternate site. Heredia, 29, appeared in eight games for Pittsburgh this season. He was 3-for-16 with two runs scored. He’s played with the Pirates, Mariners and Reds over parts of five seasons.
Dellin Betances faced his old team for the first time on Friday, pitching out of some trouble in a scoreless sixth of the Mets’ 6-4 win in Game 1.
After missing almost all of last season with arm injuries and a torn Achilles, Betances has struggled in 2020. He entered Friday’s doubleheader having allowed six earned runs in nine innings over 11 innings. He’d also given up nine hits and five walks, with seven strikeouts, as his velocity remains lower than it’s been for most of his career. According to Fangraphs, his average fastball velocity is 93.5 mph this season. In 2018, it was 97.9 mph.
“For me, I’ve got to find a way to make it work,’’ Betances said. “My pitches are cutting more this year than in the past and I have to use that as an advantage.”
He also wants to get his strikeout rate up.
“I’ve gotten guys to two strikes, but I haven’t been able to put them away like I used to with a lot of strikeouts,’’ the right-hander said. “I’ve got to learn to pitch with what I have right now.”
Betances was followed by Edwin Diaz, who earned his first save since the opening game of the season.
“He’s throwing the ball well,’’ Rojas said. “Personally, I don’t look at those stats [like saves]. It’s about how they are throwing the ball. [Diaz] has been throwing the ball really well. He’s been consistent with both of his pitches in the zone.”
Rojas said Robert Gsellman would start Saturday. … Bench coach Hensley Meulens was back with the Mets for Friday’s games. He returned Thursday, before the game against the Marlins was postponed after both teams opted not to play to protest racial injustice. That game will be made up on Monday at 1:10 p.m. at Citi Field. … Catcher Ali Sanchez got his first MLB hit in the second game.
