Absolutely incorrect. The number of strikeouts you have has absolutely no direct bearing on whether, if you put a ball in play, that ball goes for a hit. How could it? Strikeouts and balls in play are mutually exclusive. I can see the fuzzy math that is leading you to make the above incorrect statement. You're thinking of a hypothetical Player A, that in 5X at-bats (X being a very large number, such that sample size isn't an issue) doesn't hit a home run or a sacrifice fly (for the sake of keeping things simple, including them would make no difference), strikes out 2X times, makes 2X ball in play outs and amasses X hits. A .333 BABIP. Now you're thinking of a hypothetical Player B, that in 5X at-bats doesn't hit a home run or a sac fly, strikes out X times, makes 3X ball in play outs and amasses X hits. A .250 BABIP. Therefore, you're arguing, strikeouts lead to higher BABIP. Rubbish. The entire difference in BABIP is based on the completely unfounded assumption that every single extra ball in play that Player B manages instead of a Player A strikeout results in that ball in play being converted into an out. The reason that the BABIP changes is because you're changing it, you're simply making it the case that Player B hits .000 on the X extra balls in play! Obviously that's going to supress a guy's BABIP, if on X balls in play you just automatically award him with a 6-3 groundout! The drop in BABIP is entirely caused by that, and has nothing to do with the strikeouts. Player B only exists as a hypothetical, because no player is ever going to go X balls in play (where X is a very large number) and not get a single hit. What happens if you don't accidentally fiddle the numbers in your head is you end up with a player C, that in 5X at-bats doesn't hit a home run or a sac fly, strikes out X times, makes 8X/3 ball in play outs and amasses 4X/3 hits. A .333 BABIP still, only a higher average (.267 as opposed to Player A's .200). That's why it's fair to say that strikeouts suppress batting average. But they have absolutely nothing to do directly with BABIP. That said, as I mentioned before, on the whole strikeouts do have a slight indirect effect upon BABIP, in that players that strike out more, on the whole, have slightly higher BABIPs. That's simply because major league players that strike out tend to have power (because players that strike out a lot and don't have any power, unless they walk a ridiculous amount, aren't major leaguers), and power hitters tend to swing harder and thus hit the ball harder and further, meaning it is generally fielded less successfully. But striking out more isn't leading to a higher BABIP, just as striking out more isn't leading to power. It's just that they're all affected by the same thing: players "swinging for the fences" (sadly that phrase comes with a lot of negative connotations, but none are here intended). You guys are right, my apologies. I was recalling some faulty info or recalling good info badly. Thanks for the great explanation as always Diffusion.
