Bolte

De Vries put together an extremely impressive showing in Cactus League play, hitting .409 (18-for-44) with three homers and 11 RBI in 17 contests. The switch-hitting 19-year-old prodigy was the centerpiece of the Mason Miller blockbuster at the trade deadline last July and will open the minor league season at Double-A Midland. It wouldn’t be shocking at all if he reached the big leagues as a teenager in the second half. He’s one of the top 10 prospects in the entire fantasy landscape entering 2026.

Bolte is 12-for-27 in 11 games this spring. Strikeouts have been a big problem for him, but he’s a tremendous runner — he was 42-for-44 stealing bases between Double- and Triple-A last year — and if the power spike is real, he might be a sleeper this summer.

While Colby Thomas and Denzel Clarke get a lot of attention, Bolte may be just as exciting a prospect. The 22-year-old is now hitting .370/.473/.542 in 12 games since being promoted to Triple-A with one home run and four steals. The Athletics’ outfield is shaping up to be really impressive.

Bolte is the team’s sixth-ranked prospect. He slashed .278/.378/.424 with 25 extra-base hits, 42 RBIs, and 31 stolen bases in 80 games for Double-A Midland. He will join fellow prospect Colby Thomas in the outfield in Las Vegas and now puts himself in a position to earn MLB at-bats early in 2026.

Bolte also struck out twice, which makes this kind of a perfect encapsulation of who Bolte is as a player. Bolte hit 15 home runs and stole 46 bases in 2024 with a .267/.368/.466 slash line, but he also struck out 34.7 percent of the time. The fantasy value is clearly there with Bolte’s power/speed combination, but he’s not going to hit enough at the MLB level to make good on that promise if he doesn’t get his strikeout rate in check.
