Rosenthal returns to hill following groin issue

JUPITER, Fla. -- After ending Tuesday's live batting practice early due to tightness in his right groin, Cardinals closer Trevor Rosenthal returned to the mound on Sunday and threw without issue during a 25-pitch bullpen session.

Rosenthal said he expects to throw once more on the side (either a bullpen session or live batting practice) before making his Grapefruit League debut. That side session will likely come on Wednesday.

"I was lucky that it wasn't too [serious an injury] and that it was early," Rosenthal said. "I feel like I'm pretty close to being right on track."

Rosenthal did not appear to be throwing at full intensity on Sunday, though that was to be expected after the short layoff. The Cardinals believe that Rosenthal potentially prevented a more serious issue with his groin by alerting the medical staff to the discomfort immediately last week.
