DETROIT -- Everyday starters Jack Cust and Ryan Sweeney, both nursing pesky yet painful injuries, were held out of the lineup Friday.

Despite having a pair of banged-up players on his bench, manager Bob Geren said "everybody's available," although Cust and Sweeney would likely be used only in an emergency situation.

Cust and Sweeney's injuries forced Geren to concoct his 93rd different starting lineup of the season.

Cust was a late scratch from Thursday's game at Toronto because a callus on the inside of his right thumb flared up with an infection. In the batting cages before Friday's game, Cust said the thumb felt fine during most activities, but caused him pain when he gripped a bat.

"I wanted to go today," Cust said. "I just wasn't able to swing."

In Thursday's loss to the Blue Jays -- the A's season-long 10th straight -- Sweeney was pegged with a B.J. Ryan fastball on his right hand. X-rays revealed no broken bones, as the ball hit Sweeney on some soft tissue in between two fingers, Geren said.

"It's fortunate, for how hard he got hit and where he got hit, that he's OK," Geren said. "It's good news in a time where we need some."

Sweeney, who hadn't tried to swing a bat before batting practice Friday, said he could go "maybe as a last resort" if the A's needed him.
