The crossover brings together five active players: Bryce Harper, Freddie Freeman, Randy Arozarena, Junior Caminero, and Jacob Misiorowski.

Selecting emerging talents Caminero and Misiorowski alongside established stars Harper, Freeman, and Arozarena highlights the league's push to market both its veteran icons and its next wave of talent.

What to watch: Additional promotional spots from the MLB and Marvel partnership will run across national broadcasts as the 2026 World Series continues.
