From Atlantic 10 Standout to Tigers System Speedster
Selected by the Detroit Tigers in the 13th round of the 2023 MLB Draft out of Saint Joseph's University, Brett Callahan immediately established himself as one of the Atlantic 10 Conference's premier top-of-the-order threats.

- Base-Running Efficiency: Consistently converts stolen base attempts at an above 80% success rate, proving his speed translates to higher affiliate tiers.
- Defensive Versatility: Capable of playing all three outfield positions seamlessly, utilizing a strong secondary arm and sharp jump off the bat.
