The Giants placed Hunter Pence on the 10-day disabled list Monday with a left hamstring strain.
Pence missed his second straight game Sunday with hamstring tightness, and was likely to be limited to pinch-hitting had he not been placed on the DL.
Right fielder Mac Williamson was recalled from Triple-A Sacramento. Williamson is batting .274 with three home runs and 10 RBI for the River Cats.
“Hunter is one of those guys who comes in and says, ‘I feel great. I’m ready to go,’” manager Bruce Bochy said Sunday. “I’m saying this in a good way, not a negative way, but we’ve lost a little trust in him when he says he’s ready to go.
