ATLANTA -- The irony of the impending pitching matchup was not lost on Braves manager Fredi Gonzalez during his pregame meeting with the media before Friday night's game.
D-backs starter Randall Delgado, a former Braves prospect, was one of the key pieces in the trade that brought Justin Upton and Chris Johnson to Atlanta this past offseason. In return, the Braves tabbed Julio Teheran, another former prized prospect who has found a measure of consistency as a member of the Atlanta rotation all season.
As the teams discussed a possible deal involving Upton, both pitchers were mentioned as possible compensation before Arizona ultimately accepted Delgado and three other Minor Leaguers in addition to third baseman Martin Prado.
"We had to pick from one or the other, or maybe they had to pick from one or the other, and here they are, pitching against each other," Gonzalez said. "It wasn't like I called Kirk [Gibson] and said, 'I'm pitching [Teheran] on Friday, would you pitch Delgado Friday?' We'll see. I'm sure there's going to be a little competitive stuff in there."
Gattis taking it slow with oblique strain
ATLANTA -- Braves catcher Evan Gattis has yet to be cleared for baseball activities 10 days into his stint on the disabled list with a right oblique strain.
"It's a balancing act between trying to push it and trying to let it heal at the same time, so I'm just going through my treatment," Gattis said.
The 26-year-old rookie felt the muscle grab when he swung awkwardly at a slider in the seventh inning of the Braves' game against the Mets on June 17. Gattis finished the game behind the plate without getting another at-bat. He will be eligible to be activated from the 15-day DL on Wednesday, but the current pace of his healing process indicates that target may be a touch optimistic.
"He hasn't swung a bat or thrown a baseball or anything like that," manager Fredi Gonzalez said. "Everybody's oblique is different, every injury is different. You can't say, 'This is an oblique, this is 15 days.' Well, 15 days for you may be 18 for somebody else and may be 30 for somebody else."
Gattis said the Braves would wait until the area was completely free of soreness before he began any sort of rehab assignment or returned to baseball activities, but he has noticed some encouraging signs in the past few days.
"As soon as it happened, it was really sore and balled up," Gattis said. "I did get an injection that day that helped quite a bit. It was sore for a couple of days, but right after that, it felt a lot better. I think any soreness I get now is from treatment and doing my core work and all that stuff."
Gattis suffered a similar injury in the final week of the 2011 season, when he was with Class A Rome. He had the luxury of giving the muscle an entire offseason's worth of rest without treatment in that case. His current road to recovery remains on an uncertain timetable as the Braves head toward the All-Star break.
Surgery shows 'significant' damage in Pena's shoulder
ATLANTA -- Braves infielder Ramiro Pena underwent season-ending shoulder surgery on Thursday that revealed "significant" damage to the torn labrum in his right shoulder, and further highlighted the important utility-infielder void that will be filled by recent Triple-A callups Tyler Pastornicky and Paul Janish for the time being.
"A significant tear in the back of the shoulder, and we're looking at Spring Training [return]," manager Fredi Gonzalez said. "When you operate on a shoulder, it takes that amount of time."
While Pastornicky has spent the first half of 2013 adjusting to the move from everyday shortstop to everyday second baseman at the Triple-A level, he has taken some ground balls at third base since being brought back up to the Majors. Janish has entered at third base as a defensive replacement twice since being recalled by the Braves last Friday.
"We already have been giving him some ground balls at third base," Gonzalez said of Pastornicky. "He can play short and second, and you feel comfortable. Tyler's a guy that can lead off for you, he can pinch-run. He's a winning piece. We're giving him ground balls there, but obviously [Janish] would be more comfortable playing third base."
• Outfielder Jordan Schafer was in line to lead off for the fifth consecutive game before he was scratched from Friday night's lineup while still dealing with soreness from fouling a pitch off his ankle in Wednesday night's loss to Kansas City. Schafer is expected to be available for the rest of this weekend's series against the D-backs.
"He took that foul tip off the top of his foot or the ankle, so hopefully better and better every day," Gonzalez said. "He'd be the first guy you'd have to pinch-run for."
• The Braves are hoping Brandon Beachy will throw a bullpen session at some point during this week-long homestand. No timetable has been set for Beachy's resumption of a rehab assignment or any potential return to the rotation.
"He's playing catch, so we're just taking our time with him, making sure everything gets on the up-and-up," Gonzalez said.
• Reliever Luis Ayala turned in a scoreless seventh inning in his fourth rehab appearance for Triple-A Gwinnett on Thursday night, giving up a hit and striking out the final batter he faced while displaying what the Braves considered to be the best stuff he's had throughout his Minor League assignment. Ayala has been on the 15-day disabled list with an anxiety disorder since April 30.
