A's place reliever Brown on 15-day DL

Appendectomy shelves right-hander; DiNardo recalled

OAKLAND -- The A's tied a club record in 2007 by using the disabled list 22 times, and their injury woes factored in general manager Billy Beane's decision to overhaul the team with a slew of offseason trades.

When right-handed reliever Andrew Brown, who underwent an appendectomy at a Bay Area hospital Tuesday, was placed on the 15-day DL before the second game of a three-game series against the visiting Rays at McAfee Coliseum, it marked the 11th time the As have put a player on the shelf this season.

Such a pace puts Oakland, which recalled lefty reliever Lenny DiNardo from Triple-A Sacramento to fill Brown's roster spot, in line to obliterate the dubious DL mark matched last season.

Manager Bob Geren, however, suggested that his club's overall health is far better that it was in 2007, when several players who were expected to be key contributors -- Rich Harden, Mark Kotsay, Eric Chavez, Esteban Loaiza, Kiko Calero, Justin Duchscherer, Huston Street, Bobby Crosby, Dan Johnson, Milton Bradley, etc. -- missed significant chunks of the season.

"That number [11] does surprise me," Geren said. "For the most part, it feels like everybody's been available.

Brown, who didn't allow an earned run in his first 13 appearances, had allowed earned runs in his four outings prior to going on the DL. Geren said Brown was available Monday night, but had been experiencing some stomach pains over the weekend in Atlanta.

"He had a little bit in Japan, too," Geren said, referencing Oakland's season-opening series in Tokyo in late March. "I don't know if that was the same thing or not."

DiNardo, who had yet to arrive in Oakland by the time the team took the field for batting practice, was on the Opening Day roster and went 1-1 with a 10.57 ERA in four games (two starts) before being optioned to Sacramento on April 26. He opened the season in the bullpen and allowed two runs in one-third on an inning over two relief appearances before going 1-1 with an 8.59 ERA in two starts.

DiNardo was 3-1 with a 5.25 ERA in four starts with Sacramento. He allowed a .330 opponents batting average and four home runs in 24 innings.

Brown's DL stint was backdated to the day after his most recent appearance for the A's, May 14, and he is eligible for reinstatement on May 29.
