LAA@OAK: Anderson talks rehab with the FOX crew

OAKLAND -- Lefty Brett Anderson took to the mound to face hitters for the first time since April on Friday, checking off yet another significant step in his ongoing foot rehab.

Anderson simulated two innings, throwing 15 pitches each time, and another 25 warm-up pitches brought his total count to roughly 55 on the day. The next step, though not to be decided until Saturday, is most likely a rehab assignment.

"He looked good," said Nate Freiman, one of three batters to face Anderson. "His fastball had a lot of life on it, was running away from me. His breaking ball, both the slider and curveball, were sharp. His changeup had some downward action. He was attacking the zone. It's exciting to see what we could have returning to us soon."

"I can definitely see where it's not a comfortable at-bat for a lefty, that's for sure," Stephen Vogt added. "His velocity looked real good, and the ball's coming out of his hand well; his breaking ball's sharp."

Manager Bob Melvin said just as much, acknowledging the only concern at the moment was not Anderson's pitches but how his foot was progressing. It appears to be a non-issue, and the A's want to keep it that way.

"I'm glad we're not worried about his arm too much right now," Melvin said. "It's more about his foot. It certainly looks like, stuff-wise, he's close to midseason form. It's about taking the proper steps to make sure we don't get the foot back into a position where we could make it worse again, and to this point it hasn't.

"It's not surprising that he looked like he had been pitching for a while. I know he's excited about getting back sooner than later, and it would suggest that he's kept his arm in very good shape."

In what capacity Anderson returns is undecided. The A's would surely like to have him back in their rotation but also realize that placing him in the bullpen could expedite his return date.

"We'd get him back quicker if he was to be in the bullpen, but that's yet to be determined," Melvin said. "I'm glad we have the option to potentially do both with him, because usually guys that have been starters want to continue in that role. He just wants to get back and help the team in any way he can."

Grateful for time with A's, Rosales joins Rangers

LAA@OAK: Rosales makes an impressive diving stop

OAKLAND -- The A's lost one of their best defensive infielders to a division foe on Friday, with the Rangers claiming Adam Rosales off waivers.

Texas just so happens to be visiting Oakland this weekend, making for quite the easy travel day for Rosales, who carpooled to the Coliseum from nearby San Ramon with A's reliever Dan Otero, as he normally would. When he arrived at the ballpark, he simply went to the other clubhouse.

"I was excited knowing I was going to be in the big leagues still, because that's where you want to be; that's the goal," said Rosales, designated for assignment by the A's upon Alberto Callaspo's arrival Wednesday. "It's really bittersweet, though, because it's a great organization, and I feel like I grew up so much over these last four years."

Rosales got the news he was to be a Ranger when he received a call from A's assistant general manager David Forst on Friday morning. Hours later, he was speaking with new manager Ron Washington, who told him he would be playing all over the infield in a utility role.

"I thought David was calling to tell me I was going back to Sacramento," Rosales said. "Thought I'd get some at-bats, get fresh and develop down there, but he had different news for me this time. As a ballplayer, in the nature of this game, you gotta take it in stride with a grain of salt and make the adjustments I need to make as a ballplayer."

Rosales hit just .193 with a .268 on-base percentage in 50 games for the A's this year but typically provided them with solid defense, particularly at shortstop. That was why they were relieved he passed through waivers when initially designated earlier in July, only to learn of a different outcome the second time around.

"We'd probably rather it be in a different uniform, maybe in the National League somewhere that we don't play, but everyone is pretty fond of Rosie," manager Bob Melvin said, "and the fact he's back in the big leagues again is good for him, definitely.

"It is, as he said, very weird. It's probably weirder for him, but weird for us in that we have to change our signs now."

Worth noting

• Catcher John Jaso (concussion) is scheduled to have more tests Saturday, when the A's hope to have a better idea of how close he is to returning to baseball activities.

Jaso was eligible to come off the seven-day concussion disabled list Thursday.

"I know he's feeling better every day," Melvin said, "so that's a good sign."

• Josh Reddick, held out of Wednesday's game after sustaining a head injury in a three-player collision the night before, had a series of tests Friday afternoon and was subsequently cleared to return to the lineup for Oakland's series opener against Texas.

• Though Melvin planned on keeping his rotation as is through Monday and Thursday's off-days, he did mention Friday that "things could change based on performance in the coming days."

"We'll see," he said. "As I sit here right now, we'd probably look to give these guys the extra rest, and I think this is the perfect time in the season to do it."
