As the 2025 MLB trade deadline has come to a close, various blockbuster deals have garnered the spotlight. However, among the multitude of transactions, several under-the-radar moves hold the potential for significant impact. These less conspicuous transactions are often crucial for both contenders looking to bolster their rosters and rebuilding teams seeking to lay the groundwork for future success. Below, seven strategic moves are highlighted, revealing players who may exceed expectations in their new environments.

The Los Angeles Dodgers added a valuable fourth outfielder in Call, who has excelled in a part-time role, particularly against left-handed pitching. In 2025, he is batting .314 with a .443 slugging percentage in 81 plate appearances against lefties. His impressive chase rate and walk rate further underscore his potential to carve out a larger role. With the opportunity to perform well in Los Angeles, Call could create competition for playing time alongside established player Michael Conforto.

The Pittsburgh Pirates welcomed Falter, a reliable backend starter, who has demonstrated consistency since his acquisition from the Philadelphia Phillies. With a 3.73 ERA and league-average performance, he will be instrumental in providing innings, especially with key pitchers sidelined by injury. Falter's experience may allow him to compete for rotation spots and contribute to the overall stability of the pitching staff.

In Seattle, Caleb Ferguson joins the Mariners' bullpen as a middle reliever, showcasing a knack for limiting hard contact as evident from his rankings in average exit velocity and hard-hit rate. His ability to mitigate damage, particularly against left-handed hitters with a .164 batting average allowed, positions Ferguson as a valuable asset in high-leverage situations.

The San Diego Padres made a shrewd move by acquiring Fermin, who provides a more effective option behind the plate than their current catchers, Elias Díaz and Martín Maldonado. Fermin's previous success, including a 3.0-WAR campaign, positions him as an important long-term asset as the Padres aim to improve their offensive output from the catcher position.

Chicago White Sox prospect Mead, once heralded as a Top 100 talent, has faced challenges securing a regular role at the major league level due to injuries in 2025. Nevertheless, his minor league performance—boasting impressive batting averages—illustrates his potential for a breakthrough. Should he excel as a September call-up, Mead could emerge as a contender for the starting second base position in the upcoming season.

The Detroit Tigers added Paddack, who, following a stint with the Minnesota Twins, is seeking to solidify a role in the Tigers' starting rotation. In his latest appearances, he demonstrated his capabilities with a quality start against the Arizona Diamondbacks. Paddack's experience and competitive nature will aid in determining his position down the line as the Tigers aim for an effective playoff push.

Lastly, Varland joined the Toronto Blue Jays and possesses the tools to make significant contributions as a setup reliever. With a fastball that registers at an impressive 98.1 mph and effective secondary pitches, Varland's acquisition could prove beneficial for Toronto's late-inning strategies. Paired with other relievers, he enhances the Blue Jays' potential to create a formidable bullpen moving forward.
