A's Disabled and Injured List:
RHP Andrew BrownThat was quick. Brown had the surgery only five days ago and is already gearing up to return. He's still about two weeks away from rejoining the A's.
Andrew Brown, recovering from an emergency appendectomy, has begun playing catch.
RHP Kiko CaleroHe did walk two in the process. Calero has been put on a plan that would lead to his activation on May 23, the first day he's eligible to come off the 60-day DL.
Kiko Calero (shoulder) made his first appearance for Triple-A Sacramento on Saturday and struck out the side in his inning of work.
3B Eric ChavezChavez started at third base and played nine innings in Wednesday's minor league rehab game at Triple-A, going 1-for-4 with a homer.
The San Francisco Chronicle reports that Eric Chavez's (back) "most likely return date right now looks like June 6."
RHP Santiago CasillaCasilla has already started a throwing program and is said to be on track for a mid-June return.
Dr. James Andrews examined Santiago Casilla on Wednesday and agreed with the initial diagnosis of a strained elbow ligament.
IF Donnie MurphyThe plan appeared to be for Gregoria Petit to head back to the minors as soon as Mark Ellis got healthy, but he'll stick around as a backup while Murphy is out.
Athletics placed infielder Donnie Murphy on the 15-day disabled list, retroactive to May 18, with right elbow inflammation.
OF Richie RobnettThe A's have chosen not to comment on the surgery. Robnett, who had a homer and a triple in three at-bats this spring, opened this year at high-A Stockton despite turning in a solid season in Double-A last year.
A's prospect Richie Robnett is expected to miss 6-8 weeks recovering from surgery, reportedly to remove a benign tumor from his stomach.
RHP James SimmonsHe'll be examined further by team doctors. Anderson, the 26th overall pick in the 2007 draft, is one of Oakland's top prospects.
James Simmons was shut down at Double-A Midland because of what the A's believe is a dead-arm phase.
RHP Fautino De Los SantosThe newspaper doesn't go into any further details, but he was recently shut down because of elbow soreness and Tommy John surgery would sideline him for the remainder of this season and much of 2009. Acquired from the White Sox this offseason as part of the package for Nick Swisher, De Los Santos was one of the A's top prospects.
According to the San Francisco Chronicle, Fautino De Los Santos "had elbow-ligament replacement surgery this week."
LHP Brett AndersonThat explains why he gave up eight runs in one-third of an inning on Sunday. Anderson had a 2.43 ERA after six starts, but his ERA stands at 5.68 right now.
Single-A Stockton's Brett Anderson was placed on the disabled list because of a strained left thumb.

OF Chris DenorfiaThe A's announced that they'd activated Denorfia from the DL and optioned him to Triple-A last week, but the move never became official and now his back is acting up again.
Because the paperwork never went through on his previous transaction, Chris Denorfia remains on the MLB disabled list with a back injury.
OF Ryan SweeneySweeeney is probably day-to-day, but his injury could increase the chances that Frank Thomas lands on the disabled list. Rajai Davis could start in center on Thursday.
Ryan Sweeney has X-rays after Wednesday's game after fouling a ball off his left big toe.
DH Frank ThomasAn MRI exam Wednesday that showed a strain and inflammation in the area just above his knee where it connects to the quadriceps muscle. "The MRI looks pretty bad," Thomas said. "When you’re messing with a tendon that big with my age, it could rupture and that would take a long time. We’ve got plenty of time right now. They want to rest it and get the swelling out. It doesn’t bother me hitting but after last night I couldn’t push off." If Thomas goes on the DL, Travis Buck will likely be called up.
Frank Thomas could go on the disabled list with the strained quad tendon he suffered Tuesday.
