As June rolls in, major league baseball enthusiasts begin to anticipate which players may be on the trading block ahead of the July 31 trade deadline. To facilitate this discussion, Moneyline has compiled a Trade Deadline Big Board featuring the top 30 players expected to be some degree of 'available' in the coming weeks. A player qualified for this list if their team's playoff odds, as per Baseball Reference and FanGraphs, averaged below 25 percent. As of Sunday morning, this applied to only 12 teams, not all of which are likely to engage in significant trade talks.

Highlighted players, such as Paul Skenes and Oneil Cruz of the Pittsburgh Pirates, are not expected to be part of trade discussions, as reported by Bob Nightengale of USA Today, who noted that the Pirates are 'flatly rebuking' interest in Skenes and are not willing to entertain offers for Cruz. The remaining players on the list range from impending free agents to controllable talents who may be moved for various reasons, including onerous contracts or the desire to capitalize on their high market value.

The players have been ranked based on their estimated desirability leading up to the deadline. For instance, Isiah Kiner-Falefa of the Pittsburgh Pirates holds a strong average and versatility in the field, while Nathaniel Lowe of the Washington Nationals stands out despite limited power. Ramón Laureano of the Baltimore Orioles has experienced a resurgence after a prior decline, while other players such as Kenley Jansen of the Los Angeles Angels and Kenley Jansen of the Red Sox provide teams with proven capabilities in crucial moments. With the July deadline approaching, team strategies will unfold to fill roster gaps as they prepare for the final push toward the postseason.
