Been talkin’ about BABIP lately. Let’s talk about BABIP again. Let’s talk about Yasiel Puig, and his BABIP.
Last week, I wrote a post on Starling Marte, in which I examined his extraordinarily high batting average on balls in play. I had a hypothesis, and that hypothesis was confirmed. It was far from revolutionary. I knew that Marte was fast, and then I found out that he hits a bunch of line drives and never hits pop-ups. Then I also found out that those three things alone can explain more than 50% of the variance in a player’s BABIP. Again, that’s really nothing new.
The metric I created, BIP Score, featured Marte prominently near the top. Also near the top were a whole bunch of guys with BABIP’s above .330. Yasiel Puig is another guy with a BABIP above .330. It’s way above .330. During his time in the MLB, only two qualified batters have a higher BABIP than Puig. But he’s nowhere to be found in the top half of the BIP Score leaderboard. From the post:
Not everyone with a high BABIP scores well in BIP Score. Yasiel Puig, for example, owns a career .366 BABIP — higher than Marte’s — but actually has a negative BIP Score, thanks to his low line drive and average pop-up rate.
I felt like that warranted an examination of its own. This post is that examination.
I guess, first, we’ll take a look at that BIP Score. That’s how this all started anyway. To get BIP Score, I simply summed the z-scores of every qualified batter’s line drive rate, infield fly rate and speed score and scaled it so 0 was league average. It’s admittedly a quick-and-dirty metric, but the higher the BIP Score, the more likely it is that a player should be able to sustain a high BABIP.
With this methodology, Puig clocked in with a BIP Score of -0.3. To get a sense of the context, let’s look at the other guys around Puig who also clocked in at -0.3.
