In their fourth-round match, Andy Murray caught Denis Istomin on the run and forced him to hit a weak "tweener." But when Murray tried to put away the volley, he... well... couldn't. That's a bit too casual, Andy.
But later in the match, Murray lucked out on another mishit: a horrible forehand shank actually floated in and allowed him to break. That shank worked out for him, and he went on to serve out the match. The defending champion might want to clean things up a bit before facing No. 9-seed Stanislas Wawrinka in the quarterfinals on Thursday.
