With less than a month remaining in the 2026 regular season, several matchups this week will shape the playoff landscape. According to reporting, the schedule includes World Series rematches in late interleague play as teams vie for October spots.

One key series features the New York Mets (65-78) traveling to Miami to face the Marlins (72-72) in a divisional matchup with postseason implications for Florida, per Amazin' Avenue. The Mets have struggled against their division rival this year, dropping six of ten games to the Marlins, including all three contests at loanDepot Park in May.

Elsewhere, Over The Monster reported that the Red Sox, Yankees, and Rays are jockeying for playoff position in what appears to be a competitive battle in the American League. ESPN's experts offered September predictions on which teams will advance and which stat leaders will emerge down the stretch, though specifics on those forecasts were not available.
