Bingo. He's made definable and noticeable changes in hit hit profile. He's added some launch angle, and it so far has resulted in more line drives and flyballs. Because the LA change, it's something that we can trace back to a reason; it does not appear random. The flyballs may conceivably lower his batting average and yes, he may lose a single or a few that way.
To use last year's sample size, he hit 549 balls in play (I subbed out all PA's that resulted in some sort of baseball that did not land in the field of play. HR', K's, BBs, sacs, HBPs...you get the picture). Using his new numbers that would have resulted in (roughly, I'm doing some quick napkin rounding):
GB's: 181 ground balls
FB's: 209 fly balls
LD: 157 line drives
*Note this sample is two balls in play short because of rounding but it's not going to really effect the outcome, so don't @me when someone counts this as 547. I know!
Using 2025 league xBA on those results it would have resulted in the following numbers of hits. This does not differentiate between singles, doubles, triples, whatever...but it is quick napkin outcomes:
GBs: 45 hits
FBs: 37 hits (I also subtracted HR's from league xBA here for this to be fair)
LDs: 97 hits
This quick, napkin math results in 179 hits on ball in play using this quick data. Obviously this isn't entirely scientific, there are lots of other factors in play (ev, pull%, does this change his approach?) but it's not really supposed to be a scientific experiment. It's just a quick thought experiment to ballpark us. Any error isn't likely to cause egregiously different outcomes than this napkin math. Adding back in the seven home runs, he would have been at 186 hits. In 2025 Nico Hoerner recorded 178 hits. So even if someone wants to +/- 10 the amount of hits, Hoerner is right there, and that's without adding a single home run to the tally of a guy hitting the ball in the air more often.
To recap: the expected amount of hits Hoerner would lose using this approach is... seemingly none. It appears he would have had more non-home run hits based on league expected batting average. And this assumes he wouldn't hit any more home runs, which is probably unfair.
