Colton Cowser is a fantasy baseball OF prospect sleeper and minor leaguer to know. Read our MLB prospects outlooks for fantasy baseball rookies and call-ups.
PROSPECT: Colton Cowser, OF, Baltimore Orioles
ANALYSIS: The fifth overall selection in 2021 by the Orioles out of Sam Houston State, Cowser hit very well in his pro debut before posting a .278/.406/.469 slash across three levels in 2022 with 19 home runs and 18 stolen bases.
Cowser has spent all of 2023 in Triple-A, slashing .336/.477/.567 with seven home runs and five steals. He's posted a 20% walk rate and just barely higher strikeout rate, at 22%. While his glovework doesn't impact his fantasy value, Cowser is a capable center fielder who could be a high-end defender at either corner.
VERDICT: The Orioles have a glut of young outfielders in the majors and upper minors, but Cowser is by far the best of the bunch. He should be owned in all dynasty formats.

BALLER MOVE: Add in 12-team leagues CALL-UP ETA: June ANALYSIS: The Nationals went viral on social media this week for making a fun call-up. They called up their bat dog from Triple-A. While this was very cute and should improve the vibes a little bit in Washington, I don't think Bruce the Bat Dog will help […]

BALLER MOVE: Add in 12-team leagues CALL-UP ETA: June ANALYSIS: Samuel Basallo might be the best hitter in the minors right now, and he has catcher eligibility. What more do you need to know (I know catcher is super deep this year, but still)? Basallo has been an age-to-level monster for the majority of his pro […]

Andrew Painter - Fantasy Baseball Prospects Waiver Wire Stashes (Week 12)
BALLER MOVE: Add in 12-team leagues CALL-UP ETA: June ANALYSIS: Painter's last two starts don't give a ton of confidence that he is ready to be in the majors. It may not even be before the All-Star break before we see him, but that does not mean we are in stash territory. The good news is, […]

Colby Thomas - Fantasy Baseball Prospects Waiver Wire Stashes (Week 12)
BALLER MOVE: Add in 12+ team leagues CALL-UP ETA: July ANALYSIS: The A's continue to lose, and Colby Thomas continues to hit homers in Triple-A.
