Would you choose to prioritize a college degree over an immediate jump into professional sports?

Philadelphia Phillies prospect Ryan Dromboski is showing promise in the Arizona Fall League. The former University of Pennsylvania standout has limited opposing batters to a .158 average across his outings.

Why it matters

After going unselected in the 20-round 2024 MLB draft, Dromboski signed as an undrafted free agent to work his way into the Phillies system. His development in the league provides a crucial opportunity to refine his repertoire for a higher level of professional play.

Dromboski has pitched 10 2/3 innings in the Arizona Fall League while holding hitters to a .158 batting average. He also posted a 13.6 percent swinging strike rate, ranking third among all Phillies minor leaguers.

With a 13.6 percent swinging strike rate, Dromboski is demonstrating the type of miss-rate that could push him up the organization's prospect rankings. His continued development will be monitored to see if he can improve upon his 5.56 ERA from the 2026 season.

The takeaway

Dromboski serves as an example of how undrafted players can leverage developmental leagues to refine their pitch mixes and earn roles in professional rotations. Consistency in his new cutter-heavy approach remains the key for his long-term success.
