San Francisco Giants left-hander Carson Whisenhunt is diagnosed with a torn ulnar collateral ligament (UCL) in his pitching elbow, and surgery is recommended. Multiple outlets report that he exits a game after feeling sudden pain in his left elbow, then undergoes further evaluation.

Yahoo Sports and The Athletic say Whisenhunt leaves during the third inning of a 5–0 win over the Cincinnati Reds on Monday, and an MRI conducted afterward confirms the extent of the injury. The Athletic adds that the injury occurs while he is in the midst of what is described as his best start of the year. Both sources state the Giants examine him with team doctors and that surgery is likely based on the findings.

The Winnipeg Free Press similarly reports that Whisenhunt has torn his UCL in his pitching elbow and that surgery has been recommended. The outlets broadly align on the diagnosis, timing around the game, and the immediate next step following the MRI—medical evaluation and recommendation of a surgical course.
