Fantasy baseball managers, it's time to shake up your roster. This week's waiver wire brings a trio of intriguing call-ups, headlined by two speedy outfielders and a fresh arm in the Cubs' rotation. If you're looking to add some pop, speed, or pitching depth, these names deserve your attention.

First up, Henry Bolte, the Athletics' 22-year-old outfield prospect and 2022 second-round pick. Known for his raw tools but plagued by strikeouts early in his career, Bolte has turned a corner. After a standout spring training (.348/.400/.632), he's carried that momentum into Triple-A Las Vegas, where he's slashing .348/.418/.659 with 12 home runs and 17 stolen bases. Even more impressive? He's cut his strikeout rate from 35% in 2024 to just 22% this season.

But here's the catch: Bolte's power numbers come with a red flag. Despite those 12 homers, he's posting a 58% groundball rate—meaning he's rarely lifting the ball. His 44% home run-per-flyball rate is nearly four times the major league average, which screams regression. That said, his exit velocity is solid, and he'll have a major ballpark advantage: Sutter Health Park has played almost as favorably for right-handed hitters as Coors Field since the A's moved there last year.

For fantasy managers, Bolte's real value lies in his wheels. He's an elite basestealer, going 61-for-65 since the start of last season. Even if he doesn't hit for immediate power, that speed—combined with a hitter-friendly park—makes him worth a flier in mixed leagues, especially if you need steals. The A's may platoon him against lefties, and Lawrence Butler's slow start could limit playing time, but Bolte's upside is the highest of this week's call-ups.

Meanwhile, the Mets are giving 21-year-old A.J. Ewing a look. Drafted 134th overall in 2023, Ewing has built a reputation as one of the most patient hitters in the minors. His debut is a testament to his disciplined approach and ability to get on base. While his power is still developing, his knack for drawing walks and making contact could make him a sneaky add in deeper leagues.

On the pitching side, Ben Brown is the newcomer to watch in the Cubs' rotation. With Chicago's staff battling injuries, Brown gets a shot to prove himself. He's flashed swing-and-miss stuff in the minors, and if he can command his pitches, he could be a valuable streaming option down the stretch.

Whether you're chasing steals, on-base percentage, or strikeouts, this week's waiver wire has something for every fantasy manager. Just remember: Bolte's speed is the safest bet, Ewing's patience is intriguing, and Brown's arm could surprise. Happy hunting!
