The San Francisco Giants are reinstating Camilo Doval as their closer, with manager Bob Melvin announcing the change after a loss to the Tigers. Ryan Walker, who served as the closer since mid-April, will transition to a setup role despite successfully converting 10 of 12 save opportunities, though his performance has been inconsistent. Doval has excelled with a 1.16 ERA in 23 1/3 innings and is nearing a two-month scoreless streak, marking a significant return to form after struggles in the previous season, which led to a stint in Triple-A.
