David Robertson allowed an unearned run but hung on to record his 11th save of the season in Monday's win over the Cardinals. Jhonny Peralta reached on a throwing error by Derek Jeter to lead off the inning and came around to score on a Jon Jay double. However, Robertson then bowed his neck and got Matt Carpenter to ground out and Kolten Wong to strike out to end it. The Yankees closer holds a 2.40 ERA and has converted 11-of-12 save chances this season.
