The Oakland A’s called up pitching prospect A.J. Puk on Tuesday, the team announced. To make room on the 25-man roster, reliever Wei-Chung Wang was optioned to Triple-A Las Vegas on Monday. There was already an open spot on the 40-man roster, so no further move was needed there.
The left-handed Puk is one of the A’s three blue-chip, Top 100 national prospects. Entering the season he ranked as the second-best prospect in Oakland’s system, and he was within the Top 40 of most of the major national lists despite the fact that he was still recovering from Tommy John surgery.
