Philly Leader

As the Major League Baseball season approaches its final stretch, all 30 teams are set to expand their rosters in September. Each organization will have the opportunity to add two players, whether they are playoff contenders or looking ahead to next year.

In evaluating potential call-ups, MLB Pipeline focused on prospects ready for an opportunity based on team needs. Players already on the 40-man roster might have an advantage, though that isn't a barrier for all teams. Notably, twelve of the selected prospects have already experienced big league action this season.

The following is a summary of one potential impact call-up for each team:
