A's reinstate Pomeranz from disabled list

The Oakland A's have reinstated left-handed pitcher Drew Pomeranz from the 15-day disabled list and optioned right-handed pitcher Arnold Leon to Triple-A Nashville, the team announced today.

Pomeranz is 2-3 with a 4.40 ERA in eight games, all starts, with the A's this season. He was placed on the 15-day disabled list May 20 retroactive to May 19 with a sprained left AC joint. He appeared in one game on a rehab assignment with Single-A Stockton May 31, tossing 2.0 scoreless innings in a relief appearance. In parts of two seasons with the A's, Pomeranz is 1-1 with a 1.62 ERA in 10 relief appearances and 6-6 with a 3.40 ERA in 18 starting assignments.

Leon is 0-0 with a 5.06 ERA in five relief appearances over two stints with the A's this season. He was called up for the first time April 22 and made his Major League debut that day at Los Angeles-AL before being optioned back to Triple-A Nashville the next day. He went 0-2 with a 2.65 ERA in three starts with Nashville following his April 23 option, was recalled for a second time May 20 and posted a 4.15 ERA in four relief appearances.
