DENVER -- If A's manager Ken Macha had a vote, his American League All-Stars would be closer Huston Street and third baseman Eric Chavez. As for the latest round of voting released on Tuesday, Macha knew better than to expect anything positive.

"We don't get anybody in there," Macha said. "A lot of people don't vote for our guys because we're on the West Coast."

Chavez is fifth among AL third basemen with 407,628 votes, about 42,500 behind Chicago's Joe Crede. No other A's player was anywhere to be found in the balloting, not even Nick Swisher, who wasn't among the top 15 vote-getters in the outfield despite 17 homers and 46 RBIs. Chavez, who is hitting .266 with 14 homers and 46 RBIs, also trails New York's Alex Rodriguez -- a certainty to be the starter -- Boston's Mike Lowell and Toronto's Troy Glaus.

"I'd very much like to see Chavey make it," Macha said. "I went [as a coach] last year, and I was hoping he would make it and we would go together. He's won the Gold Glove the last few years, and although he's a notorious slow starter, at the end of the season, he's always around 30 homers and 100 RBIs."

Street's big month of June can only improve his chances. He has allowed one run in 12.1 innings this month, converted nine of 10 save opportunities, stranded all seven inherited runners, and held opponents to an .075 batting average (3-for-40). After a slow start, His 17 saves are fifth most in the AL.

"We'll probably end up getting a pitcher [on the All-Star team]," Macha said.

Not being on the ballot, Swisher said he has paid little attention to the voting results.

"I'm not even on the ballot, so it's no big deal," Swisher said. "But I'd like to go. I'll keep trying to be consistent, and we'll see what happens."

Even better the second time: The last thing Doug Clark was expecting after Monday night's game in Sacramento was a call to the Major Leagues. But with Milton Bradley's strained left shoulder showing no signs of improvement, and manager Macha's bench dangerously thin for games in National League parks, the A's put Bradley on the disabled list and purchased Clark's contract.

"It definitely caught me by surprise," Clark said. "I was in front of my locker after the game, a loss, and [manager] Tony [DeFrancesco] came over and announced that I was going to the big leagues. My emotions went through a swing. It was a total turnaround personally. It was nice."

Clark arrived at Coors Field around three hours before the game, but not before several phone calls to relatives and one to Mike Rouse, his former road roommate with the River Cats.

Clark, a 30-year-old left-handed hitter with speed, was hitting .290 with five homers, 31 RBIs, 45 runs scored and a team-leading 17 stolen bases in 68 games at Sacramento. He can play all three outfield positions, and was the River Cats' leadoff hitter.

He was signed as a Minor League free agent last Nov. 5, a couple of months after another unexpected call to the Majors with San Francisco. Clark already had returned home to Massachusetts after his season at Triple-A Fresno when the Giants called him up on Sept. 14. He appeared in eight games and was hitless in five at-bats.

"Last year, it was wildly unexpected," Clark said. "It's better the second time around."

Macha said Clark should be ready for an off-the-bench opportunity, especially with the A's in a stretch of nine games in NL parks. Macha's hands were tied late in Monday's game, when only Marco Scutaro, Antonio Perez and backup catcher Adam Mellhuse were healthy enough to play. Scutaro got a pinch-hitting opportunity, as Mark Kotsay needed another day off due to his stiff back, and Bradley also wasn't available.

"[Monday] would have been perfect for [Clark] -- [the A's were] down three runs, we needed somebody to get on base," Macha said.

Meanwhile, Bradley temporarily has been shut down and won't resume baseball activities until the pain subsides. The move is retroactive to June 15, meaning Bradley can come off in nine more days. But A's trainer Larry Davis said that might not be enough time for the lingering muscle strain to heal, and for Bradley to get game-ready again.

"If it takes three days for him to be pain-free, then he'll fit into that timetable," Davis said. "But if it takes longer, no. He's not very happy. He's upset about the fact that he's not available to help the team."

This is Bradley's second trip to the disabled list this season, and it comes only 15 days after he came off the list. He missed 35 games from April 27 to June 5 with a sprained right knee and a strained right oblique muscle. He is hitting .213 with three home runs and only eight RBIs in 28 games, including just .120 in seven games in between DL stays. This is his eighth trip to the DL in his career, and the 10th time the A's have had to use the DL this season -- twice more than all last season.

To clear a spot on the 40-man roster for Clark, right-hander Kaz Tadano was designated for assignment. Tadano was 0-2 with a 9.62 ERA in nine games and three starts for Sacramento.

Three more in the fold: The A's signed three more of their selections in the amateur draft -- third-round pick Matt Sulentic, an outfielder from Dallas Hillcrest High School; sixth-round pick Andrew Bailey, a right-handed pick from Wagner College; and 26th-round pick Derrick Gordon, a left-hander from Lamar University.

The A's have signed 22 of their first 29 selections, but top pick Trevor Cahill, a right-handed pitcher from Vista (Calif.) High School, remains unsigned. The A's lost their first-round pick to Washington for signing Esteban Loaiza as a free agent.

Rehab updates: After breezing through an 11-pitch inning on Monday -- nine pitches under his limit -- Justin Duchscherer (right elbow tendinitis) is scheduled to throw another inning for Triple-A Sacramento on Wednesday. He is expected to be activated for the Giants series that begins Friday. ... Joe Kennedy (left shoulder tendinitis) has another long-toss session set for Wednesday. He exceeded expectations in Monday's long toss, reaching 90 feet.

Up next: Barry Zito (8-3, 3.51 ERA) will try to make it seven wins in a row over eight starts. He has a 3.28 ERA and a .233 opponents batting average in that span, and is 7-1 with a 2.57 ERA in 10 starts since May 1. Zito will face right-hander Aaron Cook (5-7, 3.66 ERA).
