As we move into June, the focus shifts to assessing player performance and identifying potential game-changers available on the waiver wire. With the market becoming increasingly sparse, several players under 40% rostered on Yahoo leagues have emerged as promising additions.

Nick Kurtz of the Oakland Athletics, recently returned from an oblique strain, is displaying immense potential with his impressive bat speed. Despite some contact issues, his recent performance suggests a possible breakout. Meanwhile, David Festa from the Minnesota Twins has shown flashes of brilliance with a 95 mph fastball and strong secondary pitches but needs to improve his command for a consistent impact. Lastly, Jake Mangum of the Tampa Bay Rays is carving out a niche with a solid batting average and speed on the basepaths, making him a worthwhile pickup for teams in need of depth.

The Tampa Bay Rays made a significant roster move by optioning rookie Chandler Simpson to Triple-A Durham to activate outfielder Jake Mangum from the injured list. Despite Simpson's strong performance, manager Kevin Cash believes regular reps in the minors will benefit him. Mangum, coming back from a groin injury, had been hitting .338 with four doubles and seven RBIs in 21 games this season. Cash expressed confidence in Mangum's ability to perform at both center and left field, emphasizing his speed and base-running skills.

The Tampa Bay Rays have made a strategic roster move, optioning Chandler Simpson back to Triple-A Durham to accommodate the return of Jake Mangum from the injured list. Simpson's impressive start saw him collect 32 hits and 14 stolen bases in just 31 MLB games, making him a notable threat on the basepaths and drawing praise from across the league.

Simpson's speed was highlighted in a recent game against the Houston Astros, where he effectively turned a walk into a run, showcasing his ability to disrupt opposing pitchers. While his demotion might disappoint some fans, expectations remain high that he will return to the major league squad as the season progresses, particularly given his unique skill set that has already made a significant impact this year.

The early weeks of the 2025 MLB fantasy baseball season are crucial for managers seeking to capitalize on the waiver wire. Notable names to consider adding this week include Kris Bubic, who has shown potential as a reliable reliever, and Tommy Kahnle, who may be a key asset in the bullpen. Dennis Santana and Anthony Bender also stand out for their ability to contribute to pitching depth. Additionally, Victor Scott II is emerging as a noteworthy outfield option, especially with recent performance trends favoring his prospects.

As the season kicks off, fantasy managers must remain vigilant about injury updates and player performance to make informed decisions on their roster. For instance, the struggles of Thomas Harrington in his MLB debut might open up opportunities for pitchers like Bubic and Kahnle, who can help fill any gaps in starting or relief roles. Keeping an eye on standout players like Brandon Lowe, who is off to a hot start, is vital for maintaining a competitive edge throughout the season.

Josh Lowe has been placed on the 10-day injured list due to a strained right oblique, an injury that has plagued him in the past. Lowe was injured during the Tampa Bay Rays' season opener, experiencing discomfort after a foul ball. He previously missed 46 games in 2023 with a similar ailment and struggled during spring training with hip inflammation. Last season, he played 106 games, hitting .241 with 10 home runs and 25 stolen bases. To fill his roster spot, the Rays recalled Jake Mangum from Triple-A Durham.
