Law: Biggest risers and fallers from the newest MLB top-50 prospect ranking
As a companion piece to my re-ranking of the top 50 prospects in the minors — which was almost immediately undercut by the promotion of Jac Caglianone and demotion of Jordan Lawlar within days of the list going live — I've added some further notes below on six players whose outlooks have changed significantly based on the two months we've had so far, both in terms of scouts' notes and what we can see in the data.
Lewis probably would have cracked the top 50 had he played more this year, but the Reds' second-round pick from 2024 didn't make his debut this year until May 12, and even now he has barely passed 50 professional plate appearances. They've been elite, though, as he was hitting .383/.444/.574 through Monday's games with only an 18.5 percent strikeout rate, and he's already hitting the ball extremely hard, with several batted balls over 110 mph. He's in the Arizona Complex League now, and that's unusual for teams to do with a high MLB Draft pick, but I'm hopeful other teams will see Lewis' success to date and consider holding some of their teenage prospects back a little to play in the complex rather than pushing them all to Low A. There's no downside to a month in the complex to tune up before facing the better competition of full-season ball. Either way, Lewis would be on a top-75 list right now, and I won't be the least bit surprised if he's in the top 30 next winter.

Arias was the MVP of the Florida Man League last year at age 18, then ended with a credible .257/.331/.378 line in 36 games in Low A to finish his first season playing in the U.S. He went back to Low A and was so good the Red Sox bumped him up to High A before April was out. He hasn't stopped hitting since, with exceptional contact skills and breaking ball recognition already. He has whiffed on just 10 percent of the pitches he's swung at this year, which would be great for pretty much any player but is wild for a player who'll be 19 all season, playing in High A. His only real … I wouldn't even call it a flaw or a concern, but he does put the ball on the ground more often than you'd like, just over 50 percent on the season. If that improves, then we're looking at a shortstop with a plus hit tool and 20-plus homer upside. That's a prospect who ends up in the running to be No. 1 at some point.

Bonemer was the biggest enigma of the 2024 draft for me. He came into the spring a potential high first-rounder, but I got report after report that he wasn't hitting well even against mediocre competition in Michigan, and his swing seemed to change with every video I saw, starting in the fall of 2023. He has shown an advanced approach in his pro debut, with an excellent understanding of the strike zone, and the White Sox have encouraged him to go back to using the middle of the field more. That's a more natural plan for him and an improvement over his attempts to pull the ball in the air more last spring. You have to hit if you're going to hit for power. Bonemer's strong enough that the power will be there, and it's a positive sign that he's hitting as well as he is.

Sproat was at No. 30 on the list coming into 2025, thanks to a strong full-season debut in 2024 that saw him dominate High A and Double A with premium stuff across the board, although he scuffled in seven starts in Triple A to end the year. Those difficulties have continued this year, as he has a 6.02 ERA with Syracuse with just a 16.6 percent strikeout rate and 10.7 percent walk rate. The walk rate is right around the International League average, and the strikeout rate is substantially below (23.6 percent). The quality of his stuff hasn't changed much, if at all, but he now has more than twice the experience at Triple A, and hitters there haven't had much trouble connecting with all of his pitches. Nothing he has thrown has a whiff rate over 28 percent this year, and he has given up too much hard contact, especially on the fastball. Lefties are destroying him, with a .333/.420/.479 line, as his changeup is too firm and he doesn't command it, leaving it up way too often. He probably needs another pitch, or a revised changeup, for lefties so he can stay a starter, even before we get into broader questions of fastball command or what to do with the variety of breaking pitches he throws.

Smith was the White Sox's first-round pick in 2024, going at No. 5, but his Double-A debut this year hasn't gone well — he made seven starts, and in 25 2/3 innings, he walked 20 batters before hitting the IL with soreness in his left elbow. An MRI didn't show any damage, so the injury isn't a catastrophe, but his 18.7 percent walk rate puts him in the bottom 5 percent among all minor-league pitchers who've thrown at least 20 innings this year. I'm hopeful this is just a matter of a small sample where Smith may have been fighting through some discomfort and thus unable to command the ball as he has in the past. That kind of walk rate, if sustained over a larger sample, will push him to the bullpen.
Taylor was No. 89 on my top 100 coming into the year, after getting quite a bit of industry support when I talked to sources before compiling the rankings. He hit the ball consistently hard when he did hit it last year and looked like he'd be a 55 or better defender at third or second. He struck out a lot last year, however, and that's not showing any signs of abating, as he's hitting .183/.287/.327 in Double A with a 28.7 percent strikeout rate, which is at least down from 36.8 percent last year in Double A. He's 23 now and hasn't hit a lick in half a season at this level. I'm not giving up entirely, but the evidence is pretty strong that he's not going to hit.
