TEMPE, Ariz. -- Oakland A's shortstop Bobby Crosby was scratched from Monday's lineup against the Angels because of spasms in his back after fielding ground balls during warmups.

"Crosby had a little tightness in his back and we decided to scratch him," said A's manager Bob Geren, who added that he wasn't sure whether the often-injured shortstop would play on Tuesday. Crosby sat out the final two months of 2006 with a fractured vertebrae in his back.

Crosby, the 2004 AL Rookie of the year, played through rib and ankle fractures in 2005, then missed 66 games in 2006 with a fractured vertebrae in his back.

He batted a career-low .226 last year to go along with eight homers and 31 RBIs.

Crosby homered against the Rockies on Sunday.

This and that: Right-hander Joey Devine was back on the mound on Monday after his own bout with back spasms, Geren said. "He'll go on the side and throw, which is good," Geren said. Devine, though, is still expected to miss his next planned game appearance. ... Outfielder Emil Brown sat out Sunday because of a recurrence of the flu, but felt better and was working his way back to action. "He's going to go through some of the workout. He'll try to keep hydrated today and play tomorrow," Geren said. Brown last played Saturday at Scottsdale against the Giants and went 2-for-3 with an RBI and a walk. ... Outfielder Ryan Sweeney has apparently improved sufficiently from a bruised right knee and was placed on the traveling roster for Monday's tilt against the Angels. Sweeney sustained the injury this past Thursday in the Cactus League opener against the Brewers at Maryvale when he collided with Milwaukee's power-hitting first baseman, Prince Fielder. ... Right-handed reliever Kiko Calero has been rehabbing a non-surgically repaired rotator cuff injury, but has been slow in recovering. Geren said that his availability for the start of the season is now "doubtful."

Up next: The A's play the American League West rival Mariners at Phoenix Muni on Tuesday. Brown and Ryan Sweeney should be back in the lineup. Right-hander Joe Blanton is slated to make his second spring start against Seattle's Miguel Batista. Blanton was the loser in the Cactus League opener against the Brewers at Maryvale this past Thursday, allowing eight hits and six earned runs in two innings.
