Tsuyoshi Wada (elbow) threw a successful bullpen session on Monday afternoon in Orioles camp.
It was his first mound workout since undergoing Tommy John reconstructive elbow surgery last May. "I was actually very happy and it was very fun," Wada told reporters. "I have been throwing on the half-mound, so it didn't feel awkward. It wasn't much of a difference, but it was very fun." He is expected to be ready by June.
