The Mets are concerned about one of their top starters.

Tylor Megill was placed on the 15-day injured list with right biceps inflammation, the club announced on Sunday. He will undergo an MRI on Monday, until which the organization will be holding its breath in hopes of good news on their rising pitcher. Right-hander Colin Holderman was called up from Triple-A Syracuse.

The injury news arrived after Megill’s worst start of the season, to date. The righty struggled against a bottom-tier Nationals lineup last Wednesday, getting tabbed for eight earned runs on eight hits in just 1.1 innings. Just five weeks prior, Megill overpowered the very same Nationals lineup, cruising through five scoreless innings on Opening Day.

Megill’s biceps inflammation could be the reason behind his unusual disappointing outing last week. But, depending on the severity of the injury, it could also spell trouble for the Mets rotation.

Megill carried a 2.43 ERA into his meltdown at Nationals Park. His early success this season arrived at just the right time, with the injured Jacob deGrom opening the year on the IL with a stress reaction on his right scapula. Megill’s 5-2 record over seven starts into 2022 helped the organization ease the pain of losing deGrom to begin the year.
