Zobrist, whose left wrist has bothered him since the Cubs' series in Los Angeles in late May, has inflammation and was expected to get an MRI on Friday.
"It's not getting better as fast as it should be," Zobrist said. "If it's going to take another three, four days from now for it to feel great, then we're getting close to 10 days anyways. You might as well give the team the other option off the bench."
