Toshiki Sakurai tossed a bullpen session today. He threw twenty fastballs to a squatting catcher. It was his second session in as many days, first to a squatting catcher. He told reporters he no longer felt discomfort in the elbow.
Sakurai is expected to add off-speed pitches during his next session after May 16. He is hoping to make it back to the active roster in June.
