SAN FRANCISCO -- By activating right-hander Shane Loux from the disabled list and optioning down outfielder Justin Christian to Triple-A Fresno, the Giants are now going with 13 pitchers and 12 position players.
"If you look at the lineup, I'm not going to pinch-hit for a lot of these guys," manager Bruce Bochy said.
The move came after the bullpen combined for 78 pitches in Wednesday's 2-1 loss to the Mets, with four pitchers combining for four innings in relief of starter Matt Cain.
"We wanted to add an arm," Bochy said. "We had to go through our bullpen last night, and with the games coming up in Colorado, we know that can be taxing on our pitching staff."
Loux had been on the DL since June 26 with a neck strain, and Brad Penny's contract was purchased from Fresno then to take his role as the primary middle reliever.
"Shane will help out in the middle relief role," Bochy said. "You can really use him in any role. We're going to need some help after a game like yeseterday. At the same time, it helps the other pitchers when you have another pitcher to help out."
