Pence, who has been out of the Giants lineup since June 3 with tendinitis in his left wrist, put a splint back on his forearm and will be shut down for the next five to seven days, manager Bruce Bochy said.
"He's not going to take a swing for a while," Bochy said. "We've got to get this thing to calm down."
Pence took some light swings Monday and afterward met with team doctors. They recommended he put the splint back on to prevent him from taking swings and further aggravating the injury.
The Giants are 22-25 without Pence in the lineup this season. The outfielder was hitting .282 with two home runs and 13 RBIs in 71 at-bats before being placed on the disabled list for the second time this year.
• Outfielder Gregor Blanco has continued his recovery from a concussion in a positive way. Blanco said he feels much better and was able to run sprints Tuesday.
"We're going to test him pretty good," Bochy said. "Hopefully all goes well and he could be ready in the next day or so."
• Matt Cain threw 75 pitches in a rehab start for Sacramento on Monday. He threw 3 1/3 innings, giving up six hits, four runs (three earned) and two walks while striking out seven.
Cain said he is still trying to get deeper into games and Bochy said if the right-hander can do that in his next two starts, he could be ready to join the Giants' rotation soon.
"He feels great, and that's the best news," Bochy said.
