#34 – LHP Jack Leathersich

Bats/Throws: Right/Left

Height/Weight: 5’11”, 205 lbs

Acquired: 5th rd, 2011

Born: 7/14/90 (Beverly, MA)

2011 Rank: N/A

Why Ranked Here: The little lefty had an unbelievably good debut in Brooklyn in 2011, striking out over half of the batters he faced in the New York-Penn League.  His fastball sits in the low 90s, and he can reach back for 95 mph at top velocity.  His slider flashes plus.

That’s the good stuff.  The first concern with a sub-6’ pitcher is simply durability.  There just aren’t that many guys who stick in MLB rotations at that size.  Secondly, as his pitching coach, Frank Viola noted this summer, his arm angle varies, and he must do a better job repeating his delivery. Odds are, he ends up as a hard-throwing member of the bullpen.

2011: It is nearly impossible to have a better professional debut than Jack Leathersich did for the Cyclones, when he struck out over half the batters he faced. After pitching to a 1.62 ERA with 126 strikeouts against 27 walks in 89 innings for Umass Lowell, the Mets held Leathersich’s innings down by working him one inning out of the bullpen every five days.  The starter’s schedule also allowed him to throw a bullpen and a side between appearances.

Dr. Pangloss Says: He’ll be a really, really good left-handed reliever.

Debbie Downer Says:  A less impressive reliever who doesn’t make an MLB impact.

Projected 2012 Start: Savannah
