Before making his season debut with the Giants on Sunday, reliever John Brebbia had last pitched in a Major League game on Sept. 28, 2019, while with the Cardinals.

“In March 2020, Brebbia sustained a right ulnar collateral ligament tear and rehabbed from the injury before ultimately electing to undergo Tommy John surgery three months later in June.”
