Sam Sumyk, the coach of Victoria Azarenka, says fatigue was a factor in the final set of the Belarusian's 7-5, 6-7 (6), 6-1 loss to Serena Williams in the U.S. Open final. Azarenka came back from a 1-4 deficit to win the second set, but lost the last five games of the third set.
“She ran out of little bit of gas to keep pushing from behind,†Sumyk told TENNIS.com. “When you run out of energy it’s better to lead because that gives a little boost, but to push, push, push always to come back drains you.â€
