Core Incident

The Oakland Athletics placed rookie infielder Joshua Kuroda-Grauer on the 10-day injured list following emergency surgery for a ruptured testicle caused by a foul ball in the fifth inning of their 5-2 victory over the Arizona Diamondbacks at Chase Field in Phoenix on July 20. He remained in the game, recorded a single, and was later replaced at third base. The club also moved right-hander Mark Leiter Jr. to the 15-day injured list with a right hip impingement, retroactive to July 19. Right-hander Hayden Juenger and infielder Max Muncy were recalled from Triple-A Las Vegas to fill the roster spots.

Background & Recent Performance

Kuroda-Grauer was called up from the Las Vegas Aviators on June 29. In his first 16 major-league games he batted .417 with seven doubles and hit his first career home run on July 20, finishing that game 2-for-3. Mark Leiter Jr., 35, is returning from a prior hip-impingement stint that began on June 17. He has not allowed a run in 17 of his last 18 appearances, posting a 0.50 ERA over that span, and holds a season line of 0-1 with a 4.28 ERA and four saves in 36 relief outings.
