Colin Holderman

The Mets announced a series of roster moves today, with righty Tylor Megill going on the 15-day injured list, retroactive to May 12, due to right biceps inflammation. Fellow righty Colin Holderman has been selected to take his place on the active roster. To make room for Holderman on the 40-man roster, righty Trevor May has been transferred to the 60-day injured list.

The Mets didn’t provide a timeline for Megill’s injury but did say that he will undergo an MRI today. More details and the next steps should be forthcoming once the results are known.

Megill, 26, wasn’t originally projected to open the season in the rotation, but injuries to Jacob deGrom and Taijuan Walker created an opening for him. Initially, Megill took that opportunity and ran with it, making two scoreless starts to begin the season and putting up an ERA of 1.93 after five total outings. However, his last two outings haven’t been as smooth, with Megill allowing 11 total earned runs in those. It’s possible that this injury was taking its toll on him and affecting his performance.

The Mets will need another starter to take Megill’s spot in the rotation, as today is their sixth of 16 consecutive games. David Peterson would seem to be the most likely candidate to be called up, given that he’s already made three starts for the club earlier this year and performed well. But in the short term, he pitched in Triple-A on Friday and wouldn’t be available to pitch on normal rest until Wednesday. Megill’s was scheduled to start tomorrow’s game, meaning the Mets will have to figure out who’s taking the ball for that contest.

In the meantime, Holderman will join the staff to try to cover some innings. A ninth round draft pick from 2016, he’s done both starting and relieving in his minor league career, though he’s only been working out of the bullpen this year. In nine Triple-A games, he’s thrown 12 1/3 innings with a 2.92 ERA, 26.5% strikeout rate, 6.1% walk rate and 61.3% ground ball rate. As soon as he gets the call to enter a game, it will be his major league debut.

The transfer of May to the 60-day injured list isn’t shocking, as it was reported a couple of weeks ago that he will be out of action for 8-12 weeks due to a stress reaction in the humerus of his throwing arm.
