WASHINGTON -- The Braves promoted reliever Pedro Beato from Triple-A Gwinnett when David Carpenter was placed on the disabled list with right biceps discomfort on Tuesday. Before Thursday's game against the Nationals, Beato was placed on the 15-day disabled list with the same ailment.

With Beato sidelined, the Braves promoted right-handed reliever Juan Jaime to provide depth to a bullpen that has been recently taxed. After leaving Coors Field last week, the Braves played two 13-inning games within a four-day span. They also saw two of their starting pitchers last just five innings during the six-game homestand that ended Wednesday.

Beato threw 47 pitches while recording just five outs on Tuesday. He threw 13 more pitches when he returned to the mound approximately 18 hours later for Wednesday afternoon's loss to the Phillies.

Jaime has long impressed scouts and talent evaluators with a fastball that frequently touches 100 mph. But control has always been an issue for the 26-year-old hurler, who has recorded 40 strikeouts and issued 20 walks in 20 innings for Gwinnett this year.

Jaime's statistics are marred by an ugly May 4 appearance, during which he issued four walks, surrendered two hits and retired just one of the eight batters he faced. In his past 16 innings, he has surrendered seven hits, issued eight walks and retired 23 of the 60 batters he's faced via strikeout.

Still feeling light-headed, J-Up out of lineup

PHI@ATL: J. Upton leaves game with dizziness

WASHINGTON -- Braves left fielder Justin Upton is hoping the dizziness that has sidelined him the past couple of days is a product of an inner ear ailment that he might have acquired while playing four games last week in the high altitude at Coors Field.

"I've dealt with inner ear stuff before, and honestly, I hope it's that and it will blow over in the next couple of days," Upton said. "Denver can do some weird things to you. Who knows at this point? But being there for four days and playing at that altitude, you never know what can happen."

After missing Wednesday afternoon's series finale against the Phillies, Upton was hoping to return to the lineup for Thursday night's opener against the Nationals. But he still felt light-headed as he ran eight sprints on the field approximately an hour before batting practice.

"I want to get back out there as soon as possible," Upton said. "But I also want to be at full capacity and helping the team the best way I can when I do get back out there."

The veteran outfielder has been sidelined since exiting Tuesday night's loss at the end of the sixth inning.

Braves manager Fredi Gonzalez said the Braves medical staff seems encouraged with the progress made by Upton, who was comforted to learn it does not appear he's dealing with an inner ear infection. He has been told his equilibrium has likely been thrown off because of fluid in his ear.
