10:42am: The Mets have placed deGrom on the DL, retroactive to May 3, and selected the contract of lefty P.J. Conlon from Triple-A, per a team announcement. The Belfast-born Conlon has been with the Mets since they chose him in the 13th round of the 2015 draft. In his first Triple-A action this season, the 24-year-old has logged a bloated 6.75 ERA over 24 innings, despite respectable strikeout and walk rates (7.9 K/9, 2.6 BB/9).
9:50am: The Mets will place right-hander Jacob deGrom on the 10-day disabled list, Anthony DiComo of MLB.com was among those to report. The likelihood is that deGrom will only miss one start, DiComo adds.
DeGrom succumbed to a hyperextended right elbow during an at-bat Wednesday in his most recent start, though the initial fear was that he had suffered a far more significant injury. And while deGrom isn’t experiencing any symptoms at the moment, per manager Mickey Callaway, the Mets decided it would be best to act in an “overly cautious” manner in this situation. As a result, deGrom won’t take the ball Monday against the Reds. It’s unclear whether the Mets will call someone up from the minors to start in deGrom’s place or simply make it a bullpen game, according to DiComo.
As has been the case since he debuted in 2014, deGrom has been among the Mets’ elite players this season. The 29-year-old has pitched to a 1.87 ERA/2.10 FIP with 11.22 K/9, 2.28 BB/9 and a 45 percent groundball rate in seven starts and 43 1/3 innings. He and co-ace Noah Syndergaard have been the only obvious bright spots in the Mets’ rotation, which helps explain why the team has fallen off dramatically since a 12-2 start and currently owns a 17-14 record.
