"[Fans] could possibly see him pinch-hit," Bochy said. "That would be his duty today. We're going to limit him today.
"He did come out early, he swung the bat, fine swinging, ran a little bit. So he's available."
There was genuine concern that Arias would have to go on the disabled list, but Bochy said that option is not as likely.
"His progress has been about what [Giants athletic trainer] Dave Groeschner told us," Bochy said. "So I am a bit more optimistic that he's coming around."
The versatile Arias, who has played at least five games at first base, third base and shortstop, is batting .276 with 10 RBIs and 29 hits in 58 games.
