Welcome to the Majors, Daniel Schlereth

This time last year, Daniel Schlereth was waiting to be drafted by a team. The University of Arizona reliever found himself chosen by the hometown Arizona Diamondbacks in the first round. A few days ago, Schlereth got the promotion from Double-A, only he didn’t report to Triple-A, instead he jumped into the majors. Two low leverage situations later, Schlereth was tossed into the fire last night.

Entering the 8th inning, the D-Backs held a 5-1 lead over the hosting Dodgers. Tony Pena took the mound, taking over for Dan Haren after seven solid innings. Matt Kemp greeted Pena with a single, but Pena would sit down a pair of former Astros as Brad Ausmus popped out and Mark Loretta struck out. Juan Pierre would single, placing runners on the corners for Rafael Furcal, who drew a walk. Orlando Hudson would walk as well. Making it a 5-2 D-Backs lead with two outs and the bases loaded. Rather than allow Pena to face James Loney, A.J. Hinch went to the youngster to defuse the threat.

Schlereth would allow a double to Loney, allowing the bases to clear and tie the game. Casey Blake would then single, giving the Dodgers their first lead of the night. The D-Backs would face Jonathan Broxton in the ninth inning and go down 1-2-3 with a pair of strikeouts and a groundout. It’s a bit hard to peg this one on Schlereth though. A glance at his strikezone plot from Brooks Baseball in the Blake at-bat shows that he was squeezed on two strike calls:


The top and bottom of strikezones change with different hitters. Blake’s top is at the 3.58 mark and extends to 1.7. The constant is the width of the zone – or at least should be. It’s hard to argue that pitches three and four aren’t strikes, yet that’s how the umpire called it. Nobody can say for sure how a strike call on pitch three sets up pitch four or five, or if there is a pitch five, but we know how the situation played out in reality, and I’m guessing the D-Backs and Schlereth would love to try their luck with a 1-2 count instead of a 2-1 count; especially given the .300 point swing in OPS between the counts.

Schlereth gets tagged with his first major league loss, and his first major league squeezing.

Can you show where all called strikes passed your plot? Maybe the umpire’s zone was consistent.
