Actually, its worse than that. I misread the original post about 50%. I thought it was 50% not-foul, not-to the pitcher. But reading the fangraphs article, its 50% fair balls. That means the pitcher is throwing out a bunch of those (non-quantified) fair balls. Also, there is going to be some of the "not-fair balls" as outs (foul pop outs). Here was a pretty good quote from the fangraphs articleand the conclusion, which is the point most of us are trying to make: So why don’t we see more bunting against the shift? Certainly, there has to be some element of stubbornness. But it’s also just a hard thing to do, even with a lot of practice, which most shifted hitters don’t have. A foul bunt or a missed bunt is just a strike, a strike that also makes the defense aware of the bunt possibility. The pitcher, as well, becomes aware of the possibility, and might throw less buntable pitches. The math might still work out in the pro-bunt favor — I’m not close to smart enough to work all that out. But I’ve never seen bunt success rates before, and I wasn’t expecting 50%. That’s a pretty low success rate, for bunts that aren’t even necessarily successful. And against even a hypothetical awesome bunter, you can just move the guy playing short to shallow third, and then you’re not going to see many grounders hit to where the shortstop would be. And the bunt would be all but taken away. For years, it’s seemed so obvious to me. When Kyle Seager successfully bunted for a single against the shift last summer, it felt to me like a top-ten Mariners moment. If the defense wants to give the hitter an easy hit, the hitter should take the easy hit, without question. I could never understand how hitters could be so stubborn in the face of a potentially high batting average. Turns out there’s no such thing as an easy hit after all. Oh, bunt singles against the shift look easy when they’re successful, but so do Chris Davis home runs. Most of the time, Chris Davis doesn’t homer.
