Mets minor league LHP P.J. Conlon, who is transitioning to the bullpen full-time, could be an option as a second left-hander to complement Jerry Blevins.
Conlon, 24, had a 3.38 ERA and 1.24 WHIP with 108 strikeouts in 136 innings (22 starts, six relief appearances) for Double-A Binghamton last season. That included a 2.53 ERA and 1.05 WHIP with 36 strikeouts in 42.2 innings against lefties, who he has been working on refining his changeup against.
"It's kind of been my pitch for the last two seasons," Conlon recently told the AP. "When I started to come out of the `pen last year, I made it a goal of mine to start throwing it against lefties more."
Conlon grew up in California, but only became a U.S. citizen when he was 16. He was born in Belfast, Northern Ireland, and moved to the United States when he was two years old.
If he eventually reaches the Mets, he will be the first Irish-born player to appear in a big-league game since 1945, when Joe Cleary made a single relief appearance for the Washington Senators, Adam Rubin wrote last April for SNY.
The Mets have been open to adding a second left-hander to the bullpen from outside the organization, though GM Sandy Alderson suggested over the weekend that it wasn't a priority.
Right-handers Jeurys Familia, AJ Ramos, Anthony Swarzak, and Paul Sewald are expected to be in the bullpen along with Blevins, and likely three others.
The Mets might only carry seven relievers on Opening Day due to multiple off days lessening the early-season workload, but will likely carry eight relievers at most points during the season, manager Mickey Callaway suggested last week.
