Phoenix Athletics placed rookie infielder Joshua Kuroda‑Grauer on the 10‑day injured list after emergency surgery for a ruptured testicle caused by a foul ball the night before. The A’s also put right‑hander Mark Leiter Jr. on the 15‑day injured list with a right hip impingement, retroactive to July 19, before Tuesday’s game against Arizona. Hayden Juenger and infielder Max Muncy were recalled from Triple‑A Las Vegas to fill the roster spots.

Kuroda‑Grauer, who was called up June 29, was batting .417 with seven doubles in his first 16 big‑league games and had hit his first career homer in the second inning Monday. He fouled a ball into his groin in the fifth inning of the Athletics’ 5‑2 win over the Diamondbacks, fell to the ground in pain, but stayed in the game and hit a single before being replaced at third base by Donovan Walton in the sixth. Leiter, 35, has not allowed a run in 17 of his last 18 games, compiling a 0.50 ERA during that stretch, but is now out for the second time this season.

He is 0‑1 with a 4.28 ERA and four saves in 36 relief appearances overall this year.
