The Braves are well on their way to taking back a demoralizing three-game sweep at the hands of the Phillies a mere 10 days ago. Last-place Philadelphia outscored Atlanta, 21-8, to pull within 3 1/2 games of first in the NL East.
As the two clubs play the nightcap of Saturday's doubleheader, the Braves are gunning for the series win. David Hale will take the hill for Atlanta opposite Triple-A Lehigh Valley right-hander Sean O'Sullivan, who is Philadelphia's 26th man.
O'Sullivan has a 4.31 ERA in 15 starts this season for Lehigh Valley. He made three starts last season with the Padres, and is 9-15 with a 6.02 ERA in 37 career starts from 2009-13.
"He's one of the more experienced guys down there," Phillies manager Ryne Sandberg said. "He's got some experience starting in the big leagues."
Hale is typically a long-relief option out of the bullpen for Atlanta manager Fredi Gonzalez. On Saturday, Hale will make his first start since April 26, when he allowed one run over eight innings against the Reds.
Not only will the right-hander be happy to return to a starting role -- albeit briefly -- but Hale is eager to get past the struggles he has endured while compiling a 10.24 ERA in seven relief appearances this month. Two of those outings included five-run showings in the 13th inning of losses to the Angels and the Phillies over a span of three days.
"Not happy, but I'm just going to work on it," Hale said last week. "I feel like I started the year pretty well and just hit a little bit of a speed bump."
Phillies: Ruiz heads to the seven-day DL
Phillies catcher Carlos Ruiz got hit in the head with a pitch in the 11th inning Thursday, but finished the 14-inning victory over the Marlins at Citizens Bank Park.
Sandberg indicated early Friday afternoon that Ruiz was OK, although he added Ruiz's head was being monitored. But the Phillies announced an hour before Friday's 4-2 loss to the Braves that Ruiz had been placed on the seven-day concussion disabled list.
The Phillies selected the contract of Triple-A Lehigh Valley catcher Koyie Hill to take Ruiz's spot on the 25-man roster. They designated Double-A outfielder Zach Collier for assignment to make room for Hill on the 40-man roster.
Backup catcher Wil Nieves is already on the DL with a strained right quadriceps, leaving the Phillies with Cameron Rupp and Hill to catch while Ruiz and Nieves recover.
Hill, 35, was hitting .240 with nine doubles, one triple, three home runs and 17 RBIs in 45 games for Lehigh Valley.
Collier, 23, appeared in 40 games for Reading this season, hitting .228 with five doubles, two triples and one home run.
Braves: Schlosser called up from Triple-A
Major League Baseball allows teams to call up a 26th man for doubleheaders, so the Braves recalled right-hander Gus Schlosser from Triple-A Gwinnett.
Schlosser did not pitch in Game 1, making him a likely option for the nightcap. Hale has crossed the 100-pitch mark only twice in six career Major League starts.
"We'll use him whenever we need to use him," Gonzalez said of Schlosser.
The 25-year-old made the Opening Day roster, but was sent back down after posting a 4.91 ERA in 11 innings. Schlosser went 4-3 with a 4.39 ERA in 10 starts for Gwinnett.
"He went down there and started. So he could throw a lot of pitches for us," Gonzalez said. "But if we have two great starts, I hope I don't even have to use him."
• The Braves are 10-10 over their last 20 games, but they have had a good road trip so far -- with a 5-3 record with two games left to go at Citizens Bank Park.
• Sandberg said right-hander Mike Adams, who is on the disabled list with inflammation in his right shoulder, has not been cleared to begin his throwing program yet. But when the reliever is ready, he will rehab in Clearwater, Fla.
• Braves outfielder Jason Heyward has reached base safely via hit or walk in 43 of his last 46 games.
