Programming note: Dodgers-Giants coverage starts tonight at 7 p.m. on NBC Bay Area.
SAN FRANCISCO -- At some point the Giants will have to figure out how to fit NLCS star Travis Ishikawa back onto the active roster. That day has been pushed back a bit, though.
Manager Bruce Bochy said Ishikawa, who started the season on the DL because of a lower back strain, had a setback on Tuesday. Ishikawa had played five rehab games for the Triple-A Sacramento River Cats before coming to San Francisco on Friday to participate in Saturday's ring ceremony. It's unclear when he will restart the rehab assignment.
"He was hurting quite a bit," Bochy said. "He's going to need more time."
While Ishikawa isn't headed back to Sacramento in the coming days, another member of last year's team will soon join the Triple-A squad. Right-hander Erik Cordier worked out with the big league club Wednesday and will get his World Series ring on Thursday before moving on to Triple-A. Cordier (forearm tightness) struck out seven in three hitless rehab innings for the Class-A San Jose Giants.

--- Casey McGehee's bruised knee was a little sore today, so Bochy opted for Joaquin Arias at third base. Another factor: Arias has 32 career at-bats against Clayton Kershaw, third on the active roster to Buster Posey and Angel Pagan. Arias is 8 for 32 with a walk and six strikeouts against the league's best pitcher.
--- Justin Maxwell's knee is fine a day after he hit the wall, and he has a chance to win additional time. "If somebody gets hot, they'll stay in there," Bochy said of his right field situation.
--- Bumgarner carries a 5.29 ERA and .314 opponents average into his fourth start. Bochy said the only issue has been too many mistake pitches.
"He's disappointed," Bochy said. "He's made a couple mistakes, but hey, this guy is human. He's set the bar pretty high for himself."
