David Robertson hasn't allowed a run in eight innings of work this season. Robertson gave the Yankees a bit of a scare after suffering a bone bruise in his foot during spring training, but he has picked up right from where he left off last season. The 26-year-old right-hander has allowed seven hits while striking out 11 and walking only two. He won't get any save chances unless Mariano Rivera suffers an injury at some point, but he has arrived as one of the most dominant set-up men in the game.
