David Carpenter threw one inning at Triple-A Gwinnett on Saturday.

PHILADELPHIA -- Braves manager Fredi Gonzalez anticipates that reliever David Carpenter, who is on a rehab assignment, will be able to return when he's eligible Wednesday.

Carpenter has been on the 15-day disabled list since June 17 with a strained right biceps. He threw one inning at Triple-A Gwinnett on Saturday night.

"Velocity was good, arm strength was good. Threw a couple of good breaking balls," Gonzalez said of Carpenter's outing.

"When we DL'ed him, we knew that it wasn't anything major. It was right on the bicep. Some weakness there."

Carpenter is 4-1 with a 4.23 ERA and 35/8 strikeout-to-walk ratio in his fourth season.

J. Upton seeking fans' backing for All-Star berth

ATL@PHI: J. Upton robs Utley with a nice grab in left

PHILADELPHIA -- Justin Upton has posted borderline All-Star numbers in the first half, but on a Braves roster packed with talent, he's had a difficult time finding the fan support to get him an invite to the Midsummer Classic.

Upton entered Sunday hitting .281 with 16 homers, 46 RBIs and 40 runs. But in the most recent balloting, the Braves' slugger came in at ninth for outfielders in the NL. The top three vote-getters -- the Dodgers' Yasiel Puig, Pittsburgh's Andrew McCutchen and Milwaukee's Carlos Gomez -- were safely above 2,400,000 votes, while Upon had amassed 1,203,302.

Upton, an All-Star in 2009 and '11, is on a team that boasts many All-Star candidates. First baseman Freddie Freeman, catcher Evan Gattis, starter Julio Teheran and closer Craig Kimbrel have all made strong cases for selections. That fact alone has hindered Upton's chances, as even with his impressive numbers in 2014, the spotlight in Atlanta has been equally shone on a myriad of worthy players.

Still, Upton continues to give fans reason to punch his name on the ballot. Entering Sunday's contest against the Phillies, Upton was hitting .303 (10-for-33) on Atlanta's trip.
