As June unfolds, anticipation builds regarding which players might be available in the lead-up to MLB's July 31 trade deadline. To highlight this, Moneyline has compiled a Trade Deadline Big Board detailing the top 30 players who are likely to be accessible in the coming weeks. Eligibility for this list was determined by teams' playoff odds, with only those clubs averaging less than a 25 percent chance at postseason play qualifying. This criterion led to a focus on 12 teams as of the latest metrics, although not all these franchises are expected to fully engage in trade discussions.

Notably, players such as Paul Skenes and Oneil Cruz are not included in this analysis, as the Pittsburgh Pirates have reportedly declined interest in discussions regarding their prospects. According to Bob Nightengale of USA Today, the Pirates are firmly rejecting inquiries about Skenes and remain uninterested in moving Cruz. The players featured on the list range from impending free agents to controllable talent, each with their own reasons for potentially being traded. Factors may include unfavorable contracts or the strategic appeal of selling high while their value is elevated.

The players have been ranked based on perceived desirability leading up to the trade deadline on July 31.
