This is a tough one to break out of. Schneider still showed most of the positives in 2024 as he did in his short stint in 2023 and presumably his minor league breakout that same year. Even though he chased more, he still didn't chase very much - 87th percentile chase rate with a 77th percentile walk rate is plenty good on its own. The swing path is still absolutely elite, with his barrel rate and LA sweet spot rates both being in the 80th+ percentiles. These are the makings of a good hitter!
Of course then there's the bad. He's got such a small frame that even though he gets the most out of his power, the bat speed is only in the 20th percentile. That's not necessarily a death sentence on its own. Other guys within 1 mph of his bat speed include Mookie Betts, Freddie Freeman and Taylor Ward. The common denominator between those guys is elite LA sweet spot, good barrel rate and good squared up %. Schneider has 2/3 of those working! Unlike those guys, the Babe swings and misses far more frequently, generally just indicating that there's several levels of hit tool in between himself and these lower bat speed guys who succeed.
For him to find success, he needs to figure out a way to just swing and miss a bit less. That's a tall ask when the hit tool might just not be good enough to allow it. But shave a few percentage points off the whiff and K rates and we're back in business. It's also not as simple as just cheating on the fastballs. I remember in 2023 he went through a slump where pitchers started attacking him with high fastballs and he started struggling. He adjusted by being more aggressive on fastballs, and then the league countered with offspeed which he suffered with as a result. Spam fastball/changeup on a guy who can't catch up to the heat and will start cheating on it, and you got him exploited.
That's what he needs to overcome to get back into being an MLB guy. Maybe just keep it simple by platooning him against lefties as mentioned in this article, and hope he can work on the other stuff as the season moves along, hiding him from RHP unless he's showing adjustments.
