Rule 5 pick Sean Gilmartin hasn’t been used in lots of high leverage situations, but he’s been solid against lefties and has not allowed a run over his last 11.2 innings of work.

So far this season, Gilmartin has held lefties to a .244/.320/.400 line — not true LOOGY numbers, but worlds better than fellow lefty Alex Torres. Against righties, Gilmartin has been even better, holding them to a .163/.255/.208 line.

So far this season, Gilmartin has shown that he can get both righties and lefties out. And as a former starting pitcher, he can also provide the bullpen with length when needed.

If the Mets drop Gilmartin, he would have to pass through waivers, and the club would almost certainly lose him.
