Pittsburgh Pirates Prospect Watch 6/17/11


In light of Jordy Mercer’s 12th homer of the year tonight, I figured I would point out just how good he has been at the plate lately.  Mercer got off to a rough start in April, with a .154/.233/.346 line in 78 at-bats.  He did manage to hit four homers, which was one more than he hit in 485 at-bats in the entire 2010 season at the AA level.  However, the homers were about the only thing he was hitting.

Mercer started to heat up in May, and really hasn’t cooled down.  Since the month of April ended, Mercer has combined for a .317/.371/.549 line in 164 at-bats.  In 2010, Mercer hit for a .282/.329/.373 line.  The average was good, but he wasn’t getting on base, and wasn’t hitting for power at all.  So is this hot streak just a fluke, or is Mercer finally showing the potential that got him the label as an offensive minded shortstop out of the 2008 draft?

All signs point to this being legit.  First of all, Mercer has cut down on his strikeout numbers over the last few years.  In 2009 he had an 18% strikeout rate in high-A.  Last year he saw that drop to 14%.  This year it’s down to 12%.  Not only is Mercer avoiding strikeouts, he’s also seen his walk rate jump to 7.6%.  That’s not phenomenal, although it’s better than the 5.8% from 2010, and slightly better than the 7.1% in 2009.  The big thing is his BABIP.  Mercer had a .324 BABIP in 2010, when he hit for a .282 average.  This year his BABIP is just .260 for the season, and .326 during his hot streak.

Mercer isn’t hitting for a .317 average since April because he’s been lucky.  His BABIP shows that this number is legit, as it’s in line with his 2010 numbers.  His walks have been up this year, and his strikeouts are very low, giving credit to his strong on-base percentage.  The big thing with Mercer is the power.  He’s got 12 homers in 242 at-bats.  He hit 13 homers in 998 at-bats between 2009 and 2010.  He’s got half of the at-bats he had last year, and at his current pace, with 485 at-bats, he’s looking at 24 homers and 34 doubles on the year.  Considering that he can play strong enough defense to stick at shortstop, these numbers really improve his prospect status, assuming they’re legit.  And all signs point to them being legit.
