OAKLAND -- Mark Ellis and Coco Crisp continued their rehab assignments with Class A Stockton on Wednesday night and will possibly work out with the A's on Thursday before joining Triple-A Sacramento on Friday.

Ellis, who was placed on the disabled list April 21 with a strained left hamstring, joined Crisp in a rehab assignment with Stockton at Lake Elsinore on Wednesday and went 1-for-3 while playing second base. The A's second baseman is now 1-for-5 through two starts with the Ports.

Crisp, meanwhile, went 1-for-2 with a triple and a walk after enjoying a perfect 4-for-4 day with a home run and three RBIs in a start at center field Tuesday. The 30-year-old outfielder, sidelined all season with a fractured left pinkie finger, has yet to make his A's debut since signing a one-year contract with Oakland in December.

The veteran duo is slated to play with Sacramento on Friday and, depending on the results of that game, both could be back on the A's 25-man roster by the weekend.

Anderson on track to return to A's

OAKLAND -- Sometimes no news is good news regarding the A's injury front, but on Wednesday manager Bob Geren provided an uplifting update on lefty Brett Anderson.

The A's pitcher, who signed a four-year contract extension just days before exiting an outing early and subsequently being placed on the 15-day disabled list with a combination of a forearm strain and elbow inflammation, threw 41 pitches on the side at the A's Minor League complex in Phoenix on Wednesday.

Anderson, who was placed on the DL on April 27, endured the session with hitters standing in -- a situation which Geren said the recovering pitcher handled "very well."

"He's happy with the way it went," the A's skipper said. "He's coming along nicely."

Anderson was projected to miss four to five weeks, a timetable that seemingly appears to be on track. The A's, who are currently owners of a four-man rotation with Justin Duchscherer (left hip) out of the mix, could potentially see Anderson back in Oakland by the end of the month.

A's Davis back in swing of things

OAKLAND -- Rajai Davis insists his most recent struggles at the plate were not resolved with a mechanical tweak or any other change of the sort.

"It's nothing a coach could fix," the A's outfielder said Wednesday before the club took on the visiting Tigers. "It's something I had to figure out for myself."

Davis' magic marker came in the form of a mental makeover, one that put his "spiritual well-being" back in place and, subsequently, led to a .538 average over his last four games following a 29-game stretch of batting .184.

"When I'm in the Lord's presence," Davis said, "I'm more relaxed. I'm more comfortable. I'm confident. I have a different attitude."

The 29-year-old Davis was plugged in the leadoff spot at the beginning of the season, but only managed to build a .253 on-base percentage through 18 starts there. Since moving down to the bottom of the order, he has compiled a .347 OBP.

"Raj is having better at-bats," manager Bob Geren said. "We have a lot of guys like that who go through their good days and their bad days. He's been swinging the bat well."

"It's all mental," Davis said. "Everyone who gets to this level has already shown that they can play at this level. After that, it's about staying focused."
