As the MLB trade deadline approaches, some of the most prominent trade candidates are often players set to enter free agency who are performing well for teams that have fallen out of contention. These players, commonly referred to as 'rentals,' typically provide a short-term performance boost for contending teams while also enhancing their own market value ahead of free agency. Last summer, notable rental players included Jack Flaherty (traded from Detroit to Los Angeles), Yusei Kikuchi (Toronto to Houston), Tanner Scott (Miami to San Diego), Carlos Estévez (Los Angeles Angels to Philadelphia), and Jesse Winker (Washington to New York Mets). In anticipation of the upcoming trade market, Moneyline has ranked the top 25 rentals expected to be available in 2025, focusing on players' current performance, expected impact, club control, and trade likelihood.

Identifying players that may soon be on the move often begins with a look at honorable mentions, which provide a broader scope of candidates. Key position players and pitchers are outlined, including notable names like Jarren Duran, Mitch Keller, and several others who could play vital roles in future playoff pushes. Among available pitchers, Tyler Anderson (LA), Jalen Beeks (AR), Aaron Civale (CWS), and others feature prominently as teams evaluate their options leading up to the trade deadline.

Looking at individual players, one of the standout rental options is Shelby Miller, a 34-year-old reliever for the Arizona Diamondbacks. Miller has had a strong season, posting a 1.98 ERA and a 9.9 K/9 rate, although a recent forearm strain has raised concerns about his health. Another notable name, Michael Lorenzen of the Kansas City Royals, has significant trade value stemming from his previous 2024 performance, despite currently being on the injured list. Cedric Mullins of the Baltimore Orioles has struggled with his hitting recently but offers power and speed, while Josh Bell of the Washington Nationals has been a solid source of run production. Each player carries unique attributes and potential, making them intriguing options for teams eyeing improvements as they head into the 2025 season.
