OAKLAND -- If all continues to go well with his rehab work, lefty Brett Anderson could be returning to Oakland's rotation shortly after the All-Star break, manager Bob Geren confirmed Wednesday.

Anderson, placed on the 15-day disabled list on June 4 with elbow tendinitis, is completing the first week of a rehab program that is expected to last a total of 30-35 days. He is up to a throwing distance of 160 feet off flat ground and will eventually begin a round of bullpen sessions before undergoing a Minor League rehab stint.

Devine, Outman to revisit Dr. Andrews

OAKLAND -- The A's were hoping to receive help for their struggling bullpen via two familiar faces in the near future, but reliever Joey Devine and starter Josh Outman have been shut down from their respective rehab programs indefinitely.

According to manager Bob Geren, the right-handed Devine and left-handed Outman are slated to see renowned orthopedist Dr. James Andrews, who performed both of the pitchers' Tommy John surgeries last year -- Devine in April, Outman in June. Recovery time for the operation is usually around the 12-month mark, but both have experienced setbacks.

The 26-year-old Devine, who in 2008 posted a 0.59 ERA in 42 appearances with Oakland, was throwing a bullpen session every two to three days at the A's Minor League complex in Phoenix at beginning of the month and hoped to be making a rehab assignment with Triple-A Sacramento by now.

Meanwhile, Outman -- who solidified his spot in Oakland's rotation last year before suffering his elbow injury -- was progressing with his rehab work until experiencing a dose of flexor tendon soreness in early June.

"They haven't been responding the way they'd like," Geren said Wednesday. "They'll be reevaluated. They'll be shut down for a fairly extended period of time."

Geren ejected after arguing in fourth inning

OAKLAND -- Manager Bob Geren was ejected in the fourth inning of Wednesday's game against the visiting Reds following a double-play ball that the A's skipper presumably argued should have been avoided with an infield fly rule calling.

With no outs and the bases loaded, A's outfielder Gabe Gross hit a soft line drive toward Cincinnati second baseman Brandon Phillips, who watched the ball drop in front of him before trapping it in his glove and tossing it home to get Conor Jackson out at the plate. Reds catcher Ramon Hernandez then flipped the ball to third baseman Miguel Cairo for the double play, at which point Geren ran out to argue with second-base umpire Jerry Crawford.

Whether Phillips' decision to get the ball on the hop was intentional is unknown, but multiple replays showed the ball was rather low for an infield-fly-rule calling.

It marked the eighth career ejection -- second this year -- for Geren, who promptly threw his hat to the ground upon being tossed before exchanging a few more words with Crawford.

A's reach deals with four Draft picks

OAKLAND -- The A's on Wednesday agreed to terms with four players from the 2010 First-Year Player Draft.

Officially in the fold are seventh-round pick Jordan Tripp out of Golden West College and right-handed pitcher Blake Hassebrock, who was picked in the eighth round out of North Carolina-Greensboro.

Oakland also signed right-handed pitcher Josh Bowman (10th round, Tampa) and Nebraska lefty Ryan Hughes, selected in the 16th round.

The A's have now agreed to terms with 27 of their 50 picks. The first four selections remain unsigned, but Oakland has inked 15 of its 16 selections from Rounds 5-20. The final day to lock up Draft picks is Aug. 15.

Worth noting

Travis Buck has fully recovered from the strained right oblique muscle that put him on the disabled list April 22, but the A's outfielder is now experiencing leg soreness. Buck has undergone several tests for the problem, all of which have come back negative. He will receive more tests this week in hopes of continuing his rehab work. ... The A's will hold their annual Community Fund Golf Classic on Thursday, with proceeds benefiting the A's Community Fund and pitcher Craig Breslow's "Strike 3 Foundation," which he established in 2008 to help find a cure for childhood cancer. Dallas Braden, Michael Wuertz and Gabe Gross will participate in the long drive contest, while others such as Cliff Pennington, Ryan Sweeney, Daric Barton and Billy Beane are also expected to play during the day.
