Santiago Casilla, who got his third save Sunday, has earned the San Francisco Giants' closer role.

Manager Bruce Bochy had removed Sergio Romo from the closer's role, forming a closer-by-committee. But Casilla has since taken the job and run with it.

"I think it's fair to say right now," Bochy told the San Francisco Chronicle.

Casilla has two saves in his last two appearances. He has given up just one hit and struck out three in two shutout innings.

"He's got closer stuff," said left-handed setup specialist Jeremy Affeldt. "Romo has done such a great job for us the last few years. They flip-flopped them or whatever. That's the good thing about this pen. Several of us have closed before. It's not a downgrade in closers or a panic thing. It's not like we're fishing."

Romo entered Sunday's game with a 5-1 lead in the eighth inning and gave up a two-run homer to San Diego Padres switch-hitter Yasmani Grandal. Romo has surrendered a career-high seven home runs.
