Heisey: No reverse splits in minors


There has been much discussion regarding Chris Heisey's inexplicable apparent "bizarro" splits in which he has recently hit right-handed pitchers much better than lefties, which runs contrary to logic, physics, and everything my grandpa told me while seated on a barstool.

While Heisey DOES have bizarro splits in MLB over the last two years, this is likely due to the small sample size of 150 ABs vs. lefties in MLB, many of which were compiled during a lingering mid-2011 injury where he was forced into the lineup while still hurting. Additionally, Heisey has suffered a .232 BABIP vs MLB LHP, which is CRAZY low.

According to FanGraphs:

The average BABIP for hitters is around .290 to .310. If you see any player that deviates from this average to an extreme, they’re likely due for regression.

To help us understand whether he truly hits righties better than lefties, it makes sense for us to compare this small sample size to another pool of information: his minor league numbers.

Star-divide

Using minorleaguesplits.com spreadsheets, I was able to get Heisey's minor league numbers from 2008-2010 (2006 and 2007 would not load for me, so I'm calling those irrelevant for simplicity/laziness purposes).

From 2008-10 in the minors, Heisey has 342 PAs vs. RHP and 104 PAs vs. LHP.

MLB AVG vs. RHP: .288

minors AVG vs. RHP: .271

MLB AVG vs. LHP: .180

minors AVG vs. LHP: .323

MLB OBP vs. RHP: .346

minors OBP vs. RHP: .314

MLB OBP vs. LHP: .248

minors OBP vs. LHP:.400

MLB SLG vs. RHP: .539

minors SLG vs. RHP: .452

MLB SLG vs. LHP: .300

minors SLG vs. LHP: .516

MLB OPS vs. RHP: .885

minors OPS vs. RHP: .766

MLB OPS vs. LHP: .548

minors OPS vs. LHP: .916

MLB BABIP VS. RHP: .323

minors BABIP vs. RHP: .315

MLB BABIP vs. LHP: .232

minors BABIP vs. LHP:.360

So while this glance is far from perfect, I think we can see here that what we have witnessed for Heisey has been a streak of bad luck from a BABIP perspective when facing LHP at the MLB level. Get ready for some serious regression in 2012, as Heisey will likely hit righties far better than lefties.

Now we know. And knowing is half the battle!

Lefties in the Majors > Lefties in the Minors

Obviously that point is a “duh, that is why they are in the Majors” one, but I think the stuff of lefties in the Majors compared to lefties in the minors is a larger gap than the one of righties in the Majors to righties in the minors.

Another thing is that Heisey sold out for power as he got older. He steps in the bucket quite often now, trying to gain more power and get his hips rotating. That isn’t always a bad thing, because power is a good thing, but with Heisey it also leaves a large hole on the outside part of the plate that he struggles to cover. In the minors, he didn’t step in the bucket and was likely to cover more of the outside part of the plate (and lefties tend to have their pitches hit that outside corner more than righties do). I think that is part of why he struggles against lefties now and why he didn’t have such issues in the minors.

Yeah I think the bucket-stepping is the main culprit

for the weirding of his splits. I was proposing a charitable interpretation, that the reason he bails out and fares better as a PH and against RPs is that it’s a confidence issue.

But it could easily be him hitting the quad-A ceiling and only being able to master right-handed relievers in the majors. If he corrected his swing, it could be a net negative – he makes better contact against righties, but diminishes his overall power.

Should be noted

at least a handful of his starts vs LHP is because Bruce is sitting vs a tough lefty. This won’t explain it all, but a good number of his ABs vs LHP are against some of the best LHP in the game.

But honestly, I wouldn’t overthink 166 PA spread over 2 seasons. It could all just be noise.

the BABIP thing is interesting

But otherwise, yeah, I think it’s quite possible that a player who could hit lefties in the minors might find it’s far more difficult in the big leagues.

Same thing happened to Andy Phillips. He mashed lefties in the minors, but had reversed splits in the majors. I think the big league scouts found a hole in his swing. He couldn’t hit the high and away ball from a lefty, and they took advantage of that.

Question

What were his major league splits and vs. Lefty BABIP like before the 2011 injury?

What, me? Being negative? No. Never.

by Paul Householder on Jan 17, 2012 5:24 PM EST reply actions  

He barely had 200 MLB ABs before 2011, so it's a really small sample size.

Also, I don’t have the dates of his injury. Perhaps someone lese can chime in.

August 3 was the date of the injury, and it really is a small sample size

It seems he did a lot better overall (although I don’t know his splits) after he came back from the injury (.931 OPS in September) than before, so it doesn’t appear to be the injury that caused it.

What, me? Being negative? No. Never.

by Paul Householder on Jan 18, 2012 12:18 AM EST up reply actions  

Seems like...

He ran into Stubbs in late July, suffering a shoulder injury (July 25).

It was around August 3 that he suffered the oblique strain in BP that eventually landed him on the DL on August 6.

He came back on September 1 but then mashed the rest of the season.

What, me? Being negative? No. Never.

Thanks!

I’ll check that info against his game log.
