Athletics rookie Joshua Kuroda-Grauer underwent emergency surgery Monday night to repair a ruptured testicle, hours after fouling a ball directly off himself during the team's 5-2 win over the Arizona Diamondbacks. Kuroda-Grauer managed to remain in the game for another half-inning before eventually being replaced.

The incident occurred in the fifth inning, when Kuroda-Grauer crumpled to the ground after clean contact from a foul ball, prompting immediate attention from a trainer and manager Mark Kotsay. He eventually stood back up, took a few practice swings and completed his at-bat with a single.

A's play-by-play announcer Chris Caray captured the moment in a call that later went viral.

"It looks like he will come up with no balls and one strike," said Caray.

Kuroda-Grauer returned to third base for the following half-inning before being replaced in the bottom of the sixth. He finished the night 2-for-3 with his first career home run, alongside the injury. Kotsay marveled at his rookie's toughness afterward.

"I think he might be the only player in history to (rupture) a testicle, stay in the game, get a hit and play another half inning of defense," said Kotsay.

Kuroda-Grauer, a 2024 third-round pick out of Rutgers, is listed as resting comfortably following surgery, according to a team release. The injury adds to a recent run of similar incidents across baseball. Last month, Yankees second baseman Jazz Chisholm Jr. left an at-bat early after a foul ball struck him in the same area, though in that case the ball ricocheted off the ground first.

Kuroda-Grauer's situation also echoes past incidents involving Adrian Beltre, who took a comparable injury in 2009 and played through an extra-innings game, ultimately scoring the winning run. Beltre described the aftermath in past comments.

"When I look down, after the game, it wasn't a pretty sight," said Beltre. "My testicle got the size of a grapefruit. Thank God it didn't really damage anything. It took me two weeks. It was a tear. A lot of blood inside, but it didn't damage anything."
