"I'll be fine tomorrow," Avilan said following Tuesday's game. "I knew it was just a cramp, and I'll be perfect tomorrow. I'll be 100 percent tomorrow."
As the bat flew toward Avilan, he ducked and ran off the right side of the mound. He began limping following the play, and Braves manager Fredi Gonzalez pulled the left-hander before he could throw another pitch.
The injury was reminiscent of a left hamstring strain along with cramping that Avilan sustained during a relief appearance on April 16, 2013. He was not sidelined long, returning to the mound five days later.
"It looked way better this time," Avilan said. "It wasn't that bad last year, but at least this time, I knew what was going on."
Tuesday night's appearance against the Mets was Avilan's fourth of the season and lasted only one-third of an inning, like his previous three outings. He registered a hold in a 1-0 win over the Brewers on April 2 and earned a win in Friday's 2-1 victory over the Nationals.
Avilan gave up hits to both batters he faced on Tuesday. He had not allowed a baserunner in his first three appearances this season.
