From an MLB.com article on Juan Soto: "Soto had one of the best quotes about participating in the Home Run Derby last year leading up to the event. 'It might mess with the swing of all the guys that are locked in, but I think it’s going to fix mine because I’m hitting too many ground balls,' he said. 'I hope it fixes my swing trying to put the ball in the air. That’s what we’ve been trying the whole year, so I hope it fixes mine.”
"Why does that matter? Ground balls are far less likely to lead to extra bases, of course. League-wide, batters hit .453 and slugged .891 in at-bats ending on fly balls and line drives in 2021. For Soto this year, those differences have been even more pronounced, with a .252 slugging percentage on ground balls and a 1.034 mark on fly balls and line drives. Elevate, celebrate, you know the drill."
For comparison purposes, league wide in 2021 batters hit .236 total, .290 on balls in play, and slugged .413. Clearly hitting the ball in the air is more productive, but I understand matching a game plan around the talent you have.
