Braden officially named Tuesday's starter

KANSAS CITY -- It's official, pitcher Dallas Braden will return to the A's rotation Tuesday against Boston.

After missing 18 games with left elbow stiffness, A's manager Bob Geren announced that Braden will be ready to face the Red Sox.

"Unless there's a setback, he's pitching Tuesday," Geren said. "I don't anticipate a setback. His big test was his rehab start. He's thrown twice since that game and he's felt great both times."

Braden is 4-7 with a 3.83 ERA this season through 15 starts.

A's starter Brett Anderson's rehab has been moved to Triple-A Sacramento and he will start Tuesday.

Rosales making most of his opportunities

KANSAS CITY -- Adam Rosales' game-winning single in Saturday night's 6-5 victory over the Royals was par for the course during his current hot streak.

Rosales continued his dominant stretch on Sunday, going 1-for-4 with two runs scored and two RBIs, including a two-run homer that put the A's on top to stay in the fourth inning.

Rosales is now batting .410 (16-for-39) with nine RBIs and 11 runs scored in his last 12 games.

Saturday's starter Trevor Cahill said it's a relief when he sees Rosales in the lineup.

"He does a great job getting in there and playing different positions all the time," Cahill said. "I think everybody likes to see him in the lineup. He did a great job [Saturday], getting three hits in some key situations, so you can't say enough about him."

Suzuki works even on off-days

KANSAS CITY -- Though catcher Kurt Suzuki was out of the A's starting lineup for Sunday's finale against Royals, the young catcher wasn't going to rest.

Two hours before game time, Suzuki was out in the hot Kansas City sun, running sprints and stretching.

"It's good for him," A's manager Bob Geren said. "He takes care of his body, that's why he can play as much as he can. He works very hard. He does a lot of leg work through the season."

Suzuki has started in 64 games this season and is hitting .256 with 10 homers and 37 RBIs.

Geren gave Suzuki off on Sunday, but said heat was the only factor.

"It's just been very hot," Geren said. "When you catch two games in the heat like that, and then try to come back the next morning in the heat [it's tough.]"
