Henry Bolte Living Up to Expectations as a Must-Add Stolen Base Threat?
Athletics outfielder Henry Bolte has been terrific ever since being promoted to the majors for his MLB debut. Across nine big-league games, he's slashing .310/.382/.345 with an 11.8% walk rate, a 20.6% strikeout rate, and 108 wRC+. He hasn't launched a home run in the majors yet, but we knew that he didn't have a ton of power even before he was called up. He's made up for it by stealing three bases, as he continues to show off his game-changing speed. Bolte's base-stealing upside gives him a clear path to plenty of production in fantasy baseball. He's still available in 89% of fantasy baseball leagues, and he ranks as the #62 outfielder in RotoBaller's latest rankings for the 2026 season. Bolte represents a speed-centric waiver wire target as we approach the end of May.

Athletics to Promote Top Outfield Prospect Henry Bolte to Major Leagues
According to Martin Gallegos of MLB.com, the Athletics are promoting outfield prospect Henry Bolte to the major leagues. The team's No. 5-ranked prospect according to MLB.com has been swinging a hot bat at Triple-A Las Vegas this season and is being rewarded with an early promotion. Through 37 games with the Aviators, the outfielder has posted an impressive .348/.418/.658 line with a 1.076 OPS. During this stretch, Bolte has flashed high-end speed upside, swiping 17 bags while launching 12 long balls. Last summer, Bolte showed similar speed upside, stealing 44 bags over a 114-game stint in the upper minors, but had minimal power, hitting only nine round-trippers. Seeing Bolte begin to tap into his raw power makes him a priority waiver option ahead of his debut. If he sees an everyday role, Bolte could possess elite speed upside while pushing for double-digit home runs.

Henry Bolte Holds Elite Stash Upside When Looking for Speed
Athletics outfield prospect Henry Bolte holds high-end stash upside when looking for prospects who can make a high impact in the stolen base category. Through his first 36 games of the Triple-A regular season, the team's No. 5-ranked prospect has swiped an impressive 16 bags. During this stint, he has held a .351/.419/.669 slash line with seven doubles, 12 home runs, and a 38:17 K:BB. Last summer, Bolte spent most of his time with the Double-A level before joining Triple-A Las Vegas late in the second half. During his first taste of Triple-A ball, Bolte looked just as comfortable as he is now, holding a similar .300/.404/.433 line with 13 stolen bases over 34 games. Bolte has shown immense stolen base upside with increasing power. Even though there is no clear spot on the MLB roster for him, one injury could create a clear path for him. His five-category skill set makes him a top option to stash in 12+ team category formats.

Carlos Cortes Earning More Playing Time, Emerging as a Priority Waiver-Wire Target
Athletics outfielder Carlos Cortes is off to an excellent start to the 2026 season, hitting .355/.408/.570 with four home runs, 15 RBI, 11 runs scored, and one stolen base across his first 103 plate appearances of the season. Entering play on Sunday, Cortes owned an 11.1% barrel rate and had walked (eight) nearly as many times as he had struck out (nine). The 28-year-old is a bit of a late bloomer, but he posted similarly strong numbers (.866 OPS) across 99 plate appearances after making his MLB debut in 2025. The lefty-swinging Cortes appears to have worked his way into an everyday role in the corner outfield for the Athletics, at least against right-handed starting pitching. Particularly given his hitter-friendly home park in Sacramento, Cortes profiles as a viable hitting streamer for fantasy managers to target on the waiver wire.
