Saturday's happenings in Sacramento

- With the A's playing a double-header Saturday paired Joey Devine's injury, the team has elected to call up left-handed reliever Jerry Blevins and send down utility man Adam Rosales.

Blevins hasn't yielded a run in his last ten outings, lowering his ERA to 5.12. His ERA may seem high, but the lanky lefty has only allowed runs in three of his 16 appearances in with Sacramento. Left-handed hitters are only hitting .176 against him.

Blevins started the season in Oakland and was never a pitcher of record while compiling a 4.40 ERA and striking out 8.16 hitters per nine innings.

Rosales missed much of the season and all of spring training with a broken foot. Since returning to the A's June 6, Rosales has made 10 starts for the A's (five at third base, three at shortstop, one in left field and one at first base) while hitting .121 in 12 games.

- Kevin Kouzmanoff was a late scratch out of the lineup in Friday's loss to Fresno because he's suffering back-spasms. He said that the injury was caused by sitting around during the All-Star break, then trying to work out.

He said there's no way to simulate baseball activity and it's unlikely the injury would have happened if he had been on a regular baseball schedule. He's gone through back-spasms before and said he's feeling much better today than he was on Friday.

He hopes to return to action for Sunday's afternoon game where the River Cats host Fresno. Kouzmanoff has been solid since his demotion to Triple-A in early June, hitting .313 with 6 home runs and 32 RBIs in 27 games with Sacramento.

- Kouzmanoff's absence from the lineup means that Chris Carter will be playing third base for the second night in a row. Oakland is not looking at Carter to make the switch across the diamond permanently - he's only playing there out of necessity until Kouzmanoff returns.

Carter's only play at third base on Friday was a soft line drive directly at him in the first inning. He wasn't required to make any throws across the diamond.

- After spending the All-Star break representing the River Cats at the Triple-A All-Star Game, catcher Anthony Recker was moved to the DL after suffering a laceration to his left knee that prohibits him from catching. He scratched his knee on a ride-around tractor prior to Friday's game and bled profusely. Recker participated in batting practice and took ground balls at first base before Saturday night's game.

He seems unaffected by injury but will be forced to spend a minimum of seven days on the disabled list. Recker Is having an outstanding season for Sacramento, hitting .305 with 12 home runs and 36 RBIs while splitting time between first base and catcher. His .930 OPS is the third-highest on the team.
