Daichi Osera (right elbow) pitched in an indoor batting practice scrimmage at Mazda Stadium on May 25. He faced four hitters, including Hector Luna and Jason Pridie, fourteen times. He threw fastballs and off-speed pitches and allowed four could-be hits and struck out two.
If Osera does not suffer any setbacks, he could make the active roster before the end of June.
