Chris Perez converted a nail-biting save Friday, giving up two runs before stranding the tying run at first base with a strikeout to end the game. This marks Perez's second straight shaky outing, as he was battered for four runs in a non-save situation last week. Prior to that, he hadn't surrendered an earned run in his previous 14 outings. He's nailed down 33 of 37 save chances this year.
