"I really thought [Casilla] needed a day [off] last night," Bochy said. "Jeremy did a great job and we're fortunate to have a lot of guys who can do it."
After a promising start after taking over for the injured Brian Wilson in the closer's role, Casilla has struggled with a 6.89 ERA since June 1. The Giants had looked to acquire another bullpen arm before Tuesday's Trade Deadline, but no moves materialized.
"I feel good about our situation," Bochy said.
