While manager Bruce Bochy said Schierholtz's outlook is positive, he would not announce the Giants' starting pitcher for the series finale against the Astros on Wednesday.
Wednesday was Ryan Sadowski's slot in the rotation, but the Giants optioned the rookie right-hander to Triple-A Fresno on Saturday. Joe Martinez and Kevin Pucetas were both mentioned as candidates to make the start over the weekend.Pucetas pitched six innings for Fresno on Sunday, so he would not be a likely option, leaving Martinez as the probable candidate, but Bochy would not confirm what the team intends to do. "No, we're not ready yet, but we have a plan and someone in mind," Bochy said.
