The Mets bullpen struggled last year and coming into the off-season the Mets only had 1 lefty in the pen (Zamora), while the Mets are planning to rely on their new free agent signing of Wilson, they did pick up a few lefties and invited them to camp as Non-Roster Invitees, including Ryan O’Rourke.
O’Rourke was drafted by Twins in 2010 and made his major league debut in 2015. He pitched across the 2015/16 season (more on that later). Coming into 2017 he got injured and needed Tommy John and missed all of 2017. He became a free agent in November of that year and in that same month he was signed by the Orioles despite the Orioles knowing he was going to need rehab time. He did pitch in the Orioles system eventually in 2018 but didn’t see the majors and was later granted free agency. He was one of the first signings the Mets made this year on November 15th.
MLB Career: 47.0 IP, 28 G, 4.98 ERA, 1.26 WHIP, 4.38 FIP, 3.29 DRA
2018 Minors: 15 G, 14.1 IP, 1.26 ERA, 0.628 WHIP
The numbers he put up in the minors last year are significant. That’s a bounce back. He’ll probably get a long look at spring training and land himself on the short list, if healthy, for mid year call-ups / roster shakeups.
