Overview
- Whisenhunt left Monday's start at Oracle Park with left elbow discomfort after 47 pitches and the Giants won the game 5-0.
- An MRI performed the following day revealed a tear in his ulnar collateral ligament and the team said surgery was recommended.
- The club placed Whisenhunt on the 15-day injured list and recalled right-hander Spencer Bivens from Triple-A Sacramento.
- Whisenhunt has struggled for consistency this season with roughly a 6.5 ERA over eight starts, raising questions about whether elbow trouble affected his performance.
- The likely surgery would remove Whisenhunt from near-term plans, open innings for young arms like Blade Tidwell and Matt Wilkinson, and complicate the Giants' offseason search for rotation stability.
