Houston Astros prospect Forrest Whitley has suffered another setback and may end up needing Tommy John surgery.

The club released the following statement:

"Forrest Whitley has been diagnosed with a sprained ulnar collateral ligament in his right elbow. Whitley, 23, experienced discomfort in his elbow during a live BP session last week at the Astros complex. Whitley is currently seeking another opinion before finalizing plans for treatment."

Whitley has not yet debuted in the majors and posted a 7.99 ERA across four minor-league levels in 2019.
