SAN FRANCISCO -- After missing his regularly scheduled start on Monday afternoon with a strained right hamstring, it appears Matt Cain's return is imminent.
Manager Bruce Bochy said Tuesday that Cain will throw a bullpen session on Wednesday.
"If all goes well, which we anticipate it going well, then he will be pitching on Saturday," Bochy said.
Cain exited his May 21 outing against Colorado after three innings with the injury.
Cain would face St. Louis's Michael Wacha on Saturday.
