Leathersich, 24, had a 2.93 ERA (1.83 FIP) and 1.28 WHIP in 46 innings pitched spanning 37 appearances while with Binghamton. He walked a shade over four batters per nine and struck out 15.46 batters per nine.
Leathersich made a brief stop with Las Vegas in 2013, but struggled, posting a 7.76 ERA in 29 innings pitched. It should be noted that Leathersich’s BABIP against while with Las Vegas was a fluky .448.
Leathersich has to be added to the 40-man roster after the season in order to be shielded from the Rule 5 draft, so the Mets will likely add him in September and at least give him a cup of coffee in the majors.
Prior to 2014, it was often reported – including in this space – that Leathersich had reverse-platoon splits, but some have argued that his minor league sample size is too small to come to the conclusion that Leathersich won’t be effective against left-handers in the bigs.
Either way, Leathersich appears to at the very least be a big league bullpen piece. Whether he does that as a crossover guy or a lefty specialist remains to be seen, but he’s certainly an interesting arm to keep an eye on.
