Aaron Nola donned a Phillies jersey Thursday for the team's annual festival to raise money for ALS research, but it will probably be longer before Nola wears it in a game.

The 23-year-old righthander felt good after a four-inning start Wednesday at triple-A Lehigh Valley. But he threw just 52 pitches.

"The reports were good," Phillies general manager Matt Klentak said. "He felt good. . . . The only thing we still have to talk about is whether his next start is here or if he gets one more in triple A. Don't be surprised if it is one more in triple A. Obviously, we want to have that conversation with him."

Nola has not pitched in a major-league game since April 20 because of lower back soreness. In his start with the IronPigs, Nola struck out three Rochester batters and walked none. He allowed a run on four hits. He would pitch again Monday in Rochester, N.Y.

So Nick Pivetta will make his third start Friday night in Washington against the team that drafted him. The Phillies have liked Pivetta's composure, although opponents have batted .391 against him.

Still, they will be happier to have Nola back in the rotation. That could happen next weekend in Pittsburgh.

"Aaron's important," Klentak said. "We've seen Aaron at his best, and when he's at his best, he's pretty darn good. He rivals the top of anybody's rotation. He's also had his share of bumps and bruises that we need to work through, but we are committed to getting Aaron back to front our rotation."

Extra bases

The Phillies will recall Luis Garcia to replace Jake Thompson in the bullpen. Thompson was demoted after Wednesday's loss to Seattle. Garcia, who spent time with the Phillies earlier this season, had a 7.36 ERA with five strikeouts and four walks in 32/3 innings since going back to triple A. He is on the 40-man roster, so that helped his chances to return. ... Howie Kendrick (strained rib-cage muscle) will test his body this weekend in Washington with some swings and fielding work. He has not played since April 15.
