OAKLAND -- After being designated for assignment Saturday, right-handed reliever Edwar Ramirez has been outrighted to Triple-A Sacramento.

Ramirez cleared waivers after posting a 4.91 ERA in 11 innings of work over two stints with the big league club. He allowed nine hits and 10 walks while striking out 10 over that span.

Ramirez was designated for assignment to make room for outfielder Jack Cust, who is batting .316 (6-for-19) since being called up from Sacramento.

The A's also announced Friday they have released right-hander Chad Gaudin. Gaudin, who had been with the A's since Opening Day, was originally designated for assignment Sunday.

Gaudin had an 8.83 ERA in 12 appearances (17 1/3 innings pitched), which was the highest figure in the American League at the time of his designation. He was hit hard in his final two appearances, when he gave up a combined nine runs (eight earned) over 4 1/3 innings of work.

Since the departure of Ramirez and Gaudin, the A's have reshaped the bullpen by adding southpaw Cedrick Bowers and Triple-A starter Vin Mazzaro.

A's celebrate 'Dallas Braden Day'

OAKLAND -- Grandma Peggy fondly remembers the days when she would take her grandson out for a game of catch.

"He always used to tell me I look like a flamingo," Peggy Lindsey said.

Several years have passed since then, but Lindsey was given another go at it when afforded the opportunity to throw out Friday's first pitch to grandson Dallas Braden, whom she raised alone after his mother, Jodie Atwood, passed away of cancer nine years ago.

Lindsey, a lefty like her grandson, was on hand Friday to celebrate "Dallas Braden Day," as was deemed by Oakland Mayor Ron Dellums, to commemorate Braden's historic perfect game May 9.

Before the A's took on the visiting Giants, Braden was not only presented with the home plate from the perfecto but with a ring that boasted 51 diamonds on the face -- for his number -- along with 27 diamonds around the edge in honor of the 27 successive outs he recorded. Lindsey, standing alongside in the arms of Braden, received a matching pendant.

"It's been fun sharing this with Dallas," Lindsey said. "We're very close, so I wouldn't expect it to happen any other way."

The past two weeks have been something of a whirlwind for the pair, who have already taken part in TV interviews with the likes of ESPN and CBS. Despite the suddenly busy schedule, though, Lindsey is still standing on cloud 10, as Braden noted.

"My friends have all been making fun of me," she said, "saying I'm a celebrity and always seeing me on TV.

"It's been hectic, but really fun."

The A's rounded out the special pregame ceremony, which also honored Braden's perfecto batterymate, Landon Powell, by unveiling a logo on the left-field wall in memory of the game.

"This doesn't seem like it's real," Lindsey said. "It's crazy."

Ellis could return to A's on Saturday

OAKLAND -- It appears Mark Ellis' recovery is in the home stretch.

Oakland's second baseman could return as early as Saturday, when the A's continue their three-game set against the Giants.

Oakland manager Bob Geren said Ellis' status will be addressed day-to-day. Ellis, who is recovering from a strained left hamstring, will play with Triple-A Sacramento on Friday night and then update the big league club.

"Mark's close," Geren said. "He could be back really shortly or it might take a few more days. It kind of depends really on him."

Ellis has played in a pair of games with Class A Stockton this week, going 1-for-5 with an RBI and a walk, but is yet to play in a complete game. Ellis played seven innings both Tuesday and Wednesday.

"Mark feels real good at the plate," Geren said. "I just feel he needs to play at least nine innings and give it a true test every inning of the game."

Ellis joined his Oakland teammates in the clubhouse Thursday and said he felt physically fine, but that he needed to get some more at-bats in.

If Ellis is activated from the 15-day disabled list this weekend, the A's will likely have to cut loose a position player. As of Friday, the A's were carrying 12 pitchers. Oakland currently has six outfielders on its roster, including bench players Eric Patterson and Gabe Gross.
