A.J. Ewing, OF, New York Mets
Ewing had an eventful big league debut, going 1-2 with 2 R, 3B, 2 RBI, 3 BB on two hard hit balls. Ewing was a fourth round pick in the 2023 Draft and is currently the Mets No. 2 prospect and No. 78 according to MLB.com. Ewing does not have a track record of hitting homeruns in the minors. He hit 10 in 382 PAs in the low minors in 2024, but only hit 3 in 564 PA in the 2025. He started 2026 in AA, but spent 12 games recently in AAA. He had 132 upper minor PA's this season before being called up, and slashed .339/.447/.514 in those PA's with 2 homers and 17 stolen bases. He also walked (16%) more than he punched out (15%). Ewing's underlying data probably suggests there won't be much juice either. A 1.29 GB/FB is tough for someone with only a 108.8 Max EV and 34% Hard Hit rate. There could be quality of ball in play problems early. He'll walk a bit and steal bases. He comes in with a 93% zone contact rate in the minors, so he won't be a huge liability in points leagues either. I'm just really doubtful we'll get enough juice for him to be fantasy meaningful as a 21 year old in 2026.
Henry Bolte, OF, Athletics
Henry Bolte will be called up for his big league debut. He's the No. 5 prospect for the A's, and comes into his debut slashing .348/.418/.658 across 177 AAA PA's. He's hit 12 homers and stolen 17 bases. Bolte was drafted in the 2nd Round in 2022 as a high-risk, high-upside high school bat. He was largely only somewhat on the fantasy radar, as he struck out at 29% in the minors in 2025, and 35% in 2024. Severe contact issues in the minors are deeply problematic for a prospect. While Bolte isn't striking out as much, I still have my doubts. He has never posted a SwStr% below double digits. Even now, in his best minor league season, he sits at 12.4%. His zone contact has largely remained around 84%. And while Bolte has hit lots of homers thus far in the minors, he is largely a groundball machine (58% this year in AAA and 66% last year in AAA). Don't play him in redraft, and if you're in dynasty, I'd sell.
Other Notes...
Alex Bregman, 3B, Chicago Cubs
Bregman went 1-4 with a solo homer on three hard hit balls. It was an encouraging day at the plate for what has otherwise been one of the more consistent hitters in fantasy baseball. Bregman is slashing .239/.332/.688 in what is clearly a down year. His AVG and SLG are currently career-worst. He hasn't majorly declined in one area, but is down just a bit across the board. A 30 LASS and 14 LA are career worsts as well, but they are only somewhat far off from his career average. A .337 xwOBACON and .249 xBA are largely the same story. The most concerning underlying figure is his 43.4 GB%, which is a career worst. I expect some small positive regression from Bregman but he's simply not having his best season.
Shea Langeliers, C, Athletics
Langeliers went 2-4 with R, HR, 3 RBI, 2 K on two hard hit balls. Langeliers was an elite fantasy asset last year, hitting 31 homers, stealing 7 bases, and posting a .277 AVG from the catcher position. The quality of contact has taken a step forward. His 10% Barrel, 92.7 EV, 39.1% LASS, .316 xBA, .507 xwOBACON, and 47.8% HH rate are all career highs, and some by a solid margin. The impressive part about Langeliers is that you're not actually sacrificing that much contact. His 21% K rate and 25% Whiff rate are league average, and point towards continued output throughout 2026. His 20% Pull Air rate is a career-low, but it still represents a solid rate. Langeliers is a buy-high.
Jarren Duran, OF, Boston Red Sox
Duran went 0-4 with 2 K on a quiet day at the plate. Duran trended in the wrong direction in 2025 where he posted a .774 OPS after two years of crossing the .800 threshold. He now is slashing .189/.247/.315 in 2026. My main concern with Duran is he is doing less and less things well. His .360 xwOBACON and 25.7 LASS% are both career worsts. He is selling out for more power, but it isn't working. A 10% barrel rate and 13.8 LA are both career bests, but his pull air rate is down to 12.9% and his GB rate is up to 50%. An elevated LA with increased groundballs means the flyballs he's hitting are popped up, and isn't even pulling them either. I don't like the changes I'm seeing and will need him to prove it to me before considering him for any lineup of mine.
