Not a thorough or convincing use of the data regarding Larnach, IMO.
Batter BABiP does not regress to league averages as do pitchers. They don’t even regress to the player’s average…when that player is making massive adjustments. Like Larnach.
Larnach is swinging earlier in the count than he ever has. And seeming also to be willing to give in more often and try to ‘just’ put the ball in play with two strikes. Undoubtedly, to bring down the massive K rate. Regarding the K rate, it’s a monumental success. Overall, it worked for a while…but an inevitable cost is that you’ll offer at a lot of tough pitches. And pitchers adjust. So, his BB% has tanked, and whatever the averages say about EV and LA, the fact is he’s hitting a ton (for him) of balls on the ground. And it’s pretty clear he isn’t squaring stuff up as frequently as he was earlier in the year. And unless he gets significantly better at deploying this approach (certainly possible), I don’t see the HR rate bumping up much, if at all.
I would expect the BABiP to improve some…but not necessarily get too close to what it’s been in the past.
