Oakland Athletics rookie infielder Joshua Kuroda-Grauer is placed on the 10-day injured list after suffering a ruptured testicle. Multiple reports say the injury occurred during a game against the Arizona Diamondbacks on Monday, when Kuroda-Grauer fouled a ball off his groin. One account notes that despite the injury, he completes his at-bat and records a hit. Afterward, he undergoes surgery, with reporting indicating the procedure follows the injury. The Athletics’ roster move is described as an IL placement related to the ruptured testicle, using the same terminology across outlets. The injury is the primary reason for the move, and no additional on-field injury details beyond the foul tip and subsequent medical care are reported in the provided coverage. Kuroda-Grauer’s status beyond the 10-day period is not specified in these summaries.
