One of those relievers seeing plenty of action is right-hander Seth Lugo.
Lugo, 28, had a little bit of a slow start this season (1.40 WHIP, 1.86 SO/W in March/April) but has really found his groove in the month of May. In fact, he hasn’t allowed a run in 11 May innings. In that span he’s held opponents to a .132/.154/.132 slash line while striking out 13 of the 38 batters he’s faced.
The Mets final three rotation spots are currently held by Zack Wheeler and his 5.92 ERA, struggling veteran Jason Vargas that had his last start skipped and Steven Matz. The lefty Matz has allowed only two earned runs in 11 innings over his last two starts and makes him likely the Mets third best starting option.
Vargas, while he has been downright terrible (13.86 ERA), has gotten better with each start and it’s blatantly obvious he needed more than just one, 65-pitch rehab start to come back from the fracture in his right hand.
Lugo has been a vital part of a Mets bullpen that ranks eighth in the National League with their 4.03 ERA and second-to-last with a 4.33 FIP.
At some point, very soon if Wheeler and Vargas continue to struggle, the Mets have to seriously think about moving him into the rotation where he has gone 12-6 with a 4.09 ERA and 1.31 WHIP in 26 big league starts between 2016 and 2017.
“If we have the luxury of keeping him in the bullpen, that means the starters that are starting are doing pretty well and he makes our bullpen better, so we are probably a better team,” Mickey Callaway told the New York Post when asked about the possibility Lugo moving to the rotation.
Wheeler is the obvious choice for being moved out of the Mets pen given his performance this season, he can be sent to the minors and Vargas isn’t going anywhere after signing a two-year deal.
