Red Sox's Ryan Brasier: Throws off mound

Brasier (calf) recently threw a bullpen session, Christopher Smith of The Springfield Republican reports.

Brasier suffered a calf strain late in spring training and was transferred to the 60-day injured list May 3. He resumed throwing in late April and has now progressed to mound work. If Brasier remains on track in his recovery, he could make his season debut in early June.
