Waiver Wire Watch returns with under-40% rostered MLB adds for the upcoming week, highlighting hitters and pitchers who can push counting stats in multiple categories. Expect a blend of veterans back in rhythm and high-upside youngsters stepping into everyday roles, plus a handful of streamable starters for a two-start week.

Trent Grisham’s increased playing time and power surge with Judge off the everyday lineup boost his multi-category appeal in Yankee leagues. Chandler Simpson angles for a three-category payoff in Tampa Bay, while Nathaniel Lowe’s return to the middle of Boston’s order boosts counting stats upside. Colorado and Baltimore call-ups offer chance for home-heavy weeks and multi-category contributions.

Brady House, an infielder for the Washington Nationals, is making his MLB debut against the Rockies after impressive numbers in Triple-A. With a batting average of .304 and 13 home runs in 65 games, he has considerable power but also a high strikeout rate. House could be a valuable addition to your fantasy roster.

Jordan Lawlar of the Arizona Diamondbacks has shown mixed results. While his average has dipped, he boasts significant upside with five tools and could regain his form if given another chance in the big leagues. Meanwhile, Samuel Basallo from the Baltimore Orioles is another prospect to watch, showcasing power and solid walk rates.

Seattle Mariners catcher Harry Ford has been excelling in Triple-A, raising his average to .315 with 8 home runs and 3 stolen bases, making him a candidate for a call-up. Lastly, Cincinnati Reds pitcher Chase Burns, with a solid 1.83 ERA and 82 strikeouts across multiple levels, is knocking on the door of the MLB and could provide value once up.

Fantasy managers looking to bolster their rosters should pay close attention to the promising rookie prospects set to make waves in the 2025 season. Leading the charge is Roman Anthony of the Boston Red Sox, who has dazzled at Triple-A Worcester with a .303 batting average and notable power, including an impressive 497-foot grand slam. His promotion to the majors seems imminent, making him a must-add for fantasy teams.

Jordan Lawlar of the Arizona Diamondbacks has also shown significant potential despite a rough patch in the big leagues. Nonetheless, his five-tool skill set remains compelling, and a return to form could yield valuable contributions. Brady House, representing the Washington Nationals, has demonstrated improved performance with solid power numbers, suggesting he could soon be a fantasy asset. Meanwhile, Jacob Misiorowski, a pitcher for the Milwaukee Brewers, is making a name for himself with a stellar ERA and strikeout rate at Triple-A Nashville, hinting at future dominance on the mound. Lastly, Christian Moore of the Los Angeles Angels is generating buzz with his strong performance in Triple-A, showcasing his blend of power and speed that could greatly enhance any fantasy roster.

As fantasy baseball enthusiasts monitor prospect promotions, several key players have recently made their MLB debuts or are set to do so soon. Jordan Lawlar of the Arizona Diamondbacks, after a strong Triple-A season, is finally getting his chance in the majors, boasting impressive stats that include a .336 batting average and solid power-speed numbers. However, he may only play part-time, which could limit his immediate fantasy impact.

Chase DeLauter, on the mend from injuries, is expected back in action soon, and his impressive minor league numbers suggest he’s worth stashing in deeper leagues. Colby Thomas is heating up for the Athletics, hitting well and showing potential for big-league contributions, while Emmanuel Rodriguez's early struggles in Triple-A make him a less appealing option for immediate stashing. Rhett Lowder is recovering from injury and could take time before returning, but his prior performance makes him a prospect worth watching.

Keep an eye on MLB's promising prospects who could make a significant impact in 2025. Roman Anthony from the Boston Red Sox boasts a .302 batting average and solid on-base skills, despite a recent slump in extra-base hits. The Arizona Diamondbacks' Jordan Lawlar, however, has shown resilience, maintaining impressive numbers even during a dip in performance. Matt Shaw of the Chicago Cubs has also turned around after a rough start, showcasing his potential in Triple-A.

On the pitching side, Bubba Chandler from the Pittsburgh Pirates remains a top prospect with a strong 2.25 ERA, while Jacob Misiorowski of the Milwaukee Brewers has dominant strikeout potential. Additionally, Jac Caglione and Jonah Tong are also making waves in the minor leagues, proving their capability to join the majors sooner rather than later. With a focus on these talents, fantasy managers can gain a competitive edge ahead of the 2025 season.
