OAKLAND -- Hector Sanchez got the start at catcher in Friday's game against the Athletics in manager Bruce Bochy's attempt to "shake things up" for Tim Lincecum.

"You've got to keep going, keep doing what you're doing," Bochy said before Friday's game. "We just want to throw some other variables in this, make sure we cover everything."

Buster Posey started as the team's designated hitter in the first game of the Giants' final Interleague series.

"It gives Buster a break," Bochy said. "Either him or Hector were going to DH today, so I just decided to DH Buster and let Sanchez catch."

Sanchez caught Lincecum's bullpen session earlier this week in anticipation of catching him Friday, and Bochy said the move is a temporary one, even if Lincecum breaks out of his season-long slump with Sanchez behind the plate.

"This isn't the way it's going to be, just today," Bochy said. "It's just a little thing that you do occasionally with your club to shake things up."

Sanchez has served as the team's backup catcher, though he has been the primary catcher for starter Barry Zito. Bochy said he could make a similar move and have Posey catch Zito.

"Buster's our catcher," Bochy said. "It's nothing to do with Buster. He'll be catching Timmy. We have a lot of baseball left. It's pretty much a one-time deal."

Pagan out to rest abdominal strain

OAKLAND -- Angel Pagan was out of the lineup for Friday's game against the Athletics, with Gregor Blanco shifting over from right field to start in center and Nate Schierholtz getting the start in right.

Pagan has been playing with a strained abdominal muscle, and Giants manager Bruce Bochy said Pagan would most likely be the team's designated hitter Saturday. With Thursday's off-day, that would give Pagan three days off from the outfield.

"He's doing better, but this was the plan to give him another day," Bochy said. "It's still there, but it's going away."

After batting .375 in 27 games in May, Pagan has hit .254 in 18 games in June, including going 6-for-36 (.167) in the last nine games.
