The Mets moved 26-year-old starting pitcher Tylor Megill to the 15-day IL after imaging revealed right biceps tendinitis.Tylor Megill Injury UpdateMegill suffered through 1-and-a-third innings on May 11, allowing eight earned runs on eight hits and two home runs, by far the worst outing of his young career. The IL placement is retroactive to May 12, signaling that he began feeling soreness and underwent an MRI the day after his start. He will be eligible to return on May 27, but as the Mets are doing with Jacob deGrom's current arm issues, New York will likely be cautious with Megill's recovery.He will be shut down from throwing for at least the next few days before being re-evaluated later this week. The second-year major leaguer was tabbed as the Opening Day starter after a slew of injuries thinned out the rotation. Megill had a 2.43 ERA with 25 strikeouts through his first four starts, adding five innings in the Mets' combined no-hitter against the Phillies on April 29.Megill was scheduled to start on Tuesday, which will now be the second part of a doubleheader, but Buck Showalter has yet to name his replacement in the rotation.
