OAKLAND -- When the July 31 non-waiver Trade Deadline comes and goes, it will likely do so without much noise from the A's. Listening to Oakland general manager Billy Beane on Friday, it sounds like Ben Sheets and Coco Crisp will still be members of the A's in August.

"Regardless of where we finish this year," Beane said, "I think it's important to build some momentum and I think that would require us to hold on to our guys. ... In a general sense, I don't expect us to be very active, because I'd like to keep the guys that are here around."

Beane also directly addressed the trade rumors surrounding Sheets, who has garnered the attention of several teams. Sheets, who signed a one-year, $10 million deal with the A's in the offseason, is 4-9 with a 4.53 ERA in 20 starts.

"I think he's been an important part on the field," Beane said. "I also think he's been very influential in the clubhouse with all these young guys. He's been a great addition personality-wise and I think he keeps the players loose; he's a competitor on the mound. I think it would behoove us to keep a guy like that around."

But Beane wouldn't go so far as to speculate on Sheets' contract status after the season, saying, "We'll get to that."

Anderson in the mix for Sunday's start

OAKLAND -- Southpaw Brett Anderson rejoined the A's on Friday and threw a bullpen session, but Oakland manager Bob Geren didn't say who would start Sunday's series finale against the White Sox.

Anderson hasn't pitched for the A's since June 3 because of left elbow inflammation. Geren said Anderson, Dallas Braden and Ben Sheets are all being considered to start Sunday.

"I'll prepare like I'm throwing on [Sunday] until they tell me different," Anderson said.

The 22-year-old Anderson, widely regarded as the team's most talented pitcher, threw 83 pitches in a rehab start for Triple-A Sacramento on Tuesday. If Anderson was to stay on four days' rest, he would pitch on Sunday. The same can be said for Braden, who finished 4 2/3 innings for the A's against the Red Sox on Tuesday.

Geren said the team will likely make the decision by Saturday. Anderson said he was a limited in his last rehab start and couldn't throw all the breaking balls he wanted to, but that he had no such problems during Friday's side session.

"It was my normal bullpen," Anderson said. "I threw all my pitches good, so it's on to the next start, whenever that might be."

After going 11-11 with a 4.06 ERA in his rookie season last year, Anderson has gone 2-1 with a 2.35 ERA in six starts this season. Anderson is currently on the 15-day disabled list for the second time this season, having missed 30 games with similar elbow problems from April 25-May 28.

"It's never fun being on the DL," Anderson said. "You always want to be able to help your team win. I think I have pretty good capabilities to do that and I was off to a pretty good start before I got hurt. But there's nothing you can do about it now, you just got to pick up where you left off and try to win some ballgames."

Prospects await call at Triple-A

OAKLAND -- Though he came to the A's dugout before Friday's game against the White Sox to discuss Kurt Suzuki's extension, general manager Billy Beane eventually digressed toward the development of several high-profile Minor League players.

Chief among them are, of course, Chris Carter and Michael Taylor. Carter and Taylor have long been discussed in the same breath, as the potential sluggers are still in Triple-A Sacramento awaiting their promotions. Beane was largely non-committal when discussing if and when Carter and Taylor would be called up.

Carter, who had played 90 of 96 games at first base entering Friday, is batting .241 with 23 home runs and 71 RBIs this season. Taylor, who has five home runs and 58 RBIs, toted a 17-game hitting streak entering play Friday and is batting .379 (25-for-66) in that span to raise his season average to .275.

"Chris has been hitting for extra bases the whole year," Beane said. "He's been consistently driving the ball -- we got to get the average up a little bit. Michael was hurt -- in May he was out for three weeks -- and he's starting to swing the bat. Both of them are starting to swing the bat real well, it's been fun going to the box scores."

Beane said he sees Taylor playing left field at the Major League level, while saying Carter has the physical tools to play in the outfield as well. But Beane said it wouldn't do Carter any good to come up to the Majors and serve as a designated hitter.

"We'll keep him at first right now," Beane said. "He's a pretty good athlete, so I don't think [Carter playing outfield] is out of the realm of possibility. We talked about that in the spring, but if he hits and hits for power we'll find a spot for him."

Beane also commented on the success of 2009 first-round pick Grant Green, who recently played in the All-Star Futures Game during the All-Star break in Anaheim. Green is batting .332 with 10 homers and 50 RBIs for Class A Stockton this season.

"His last six weeks have been absurd," Beane said. "Slugging, batting average. I was looking at some of his numbers the other day and I said, 'Holy cow.'"

Beane also said prized international free-agent signee Michael Ynoa has suffered from a recent bout of tendinitis, but that Ynoa will start throwing again this week.
