Grilli logged his tenth save of the season, allowing just a walk in a scoreless ninth inning as the Braves defeated Miami 5-3 Friday night. Grilli suffered some back spasms a few days ago, and had a couple of shaky outings after returning to his bullpen duties. He followed Jim Johnson to the hill after Johnson twirled a scoreless eighth inning in this one, and appears to be secure in his closer's role.
