As the MLB trade deadline approaches, a common trend emerges: players heading towards free agency and excelling on teams that are no longer in contention become prime trade candidates. Often termed as "rentals," these athletes are sought after for their ability to provide immediate impact for contending teams while simultaneously enhancing their value before hitting the open market. Last summer, notable players such as Jack Flaherty, Yusei Kikuchi, Tanner Scott, Carlos Estévez, and Jesse Winker exemplified this trend as they transitioned to new teams.

In anticipation of the upcoming trade deadline, analysts have compiled a list ranking the top 25 rental candidates for the 2025 MLB trade market. The rankings take into account players' current performance, potential impact on their new teams, remaining club control, and the likelihood of being traded. To provide a comprehensive overview, here are some honorable mentions for teams expected to engage in trades: Jarren Duran, Mitch Keller, alongside a selection of non-rental targets.

Starting with the list, players such as Shelby Miller of the Arizona Diamondbacks, who has enjoyed a successful season with a 1.98 ERA, and Michael Lorenzen of the Kansas City Royals, who has a 4.61 ERA, have been highlighted. Cedric Mullins of the Baltimore Orioles provides power and speed despite recent struggles at the plate. Similarly, Josh Bell of the Washington Nationals demonstrates consistent offensive production, contributing to his team's performance. Throughout the list, both pitchers and hitters such as Charlie Morton, Gregory Soto, and Ryan Helsley are considered vital components as contenders look to bolster their rosters ahead of the playoff push.
