CHICAGO — Right-handed pitcher Ryan Vogelsong is back in the starting lineup while the newest San Francisco Giants pitcher — right-hander Mike Leake — is temporarily out.
Giants manager Bruce Bochy said prior to Thursday’s series opener against the Chicagi Cubs a that Leake has a strained left hamstring and will not start Friday’s second game.
Vogelsong will return to the rotation — at least for one day — and pitch in Leake’s place.
Leake could miss one start, or maybe more. Giants manager Bruce Bochy wasn’t sure.
“No guarantee,” Bochy said. “In a couple of days, we’ll make a call.”
The hamstring strain was found during an MRI examination.
Leake, acquired from the Cincinnati Reds prior to last week’s trading deadline, worked 6 2/3 innings in his first Giants outing — a 2-1 loss to the Texas Rangers on Sunday.
Vogelsong’s last outing was Monday at Atlanta with a blown save in the Giants’ 9-8 loss in 12 innings.
He switched to the bullpen after the All-Star break following the return of Tim Hudson from the disabled list. Vogelsong has allowed 11 runs (seven earned) in 11 2/3 innings of relief, covering eight appearances.
