Marlins LHP prospect Thomas White has been diagnosed with a left shoulder capsular strain and is likely to miss the rest of the season.
White is scheduled to return in 12-16 weeks, which ostensibly rules out any possibility of him pitching again this season. The 21-year-old southpaw is universally-regarded as one of the top pitching prospects in baseball and appeared to be on the verge of reaching Miami after posting a 4.01 ERA and 35/15 K/BB ratio across 24 2/3 innings across seven starts for Triple-A Jacksonville this season. Shoulder issues are complicated matters, but all signs point to White being a full-go by spring training following a relatively normal offseason. It’s a significant hit to his dynasty stock and eliminates any chance that he reaches the big leagues this season.
