Bernard Tomic has admitted that he has no complaints following Friday's defeat to Andy Roddick in the second round of the US Open.

The Australian was beaten 3-6 4-6 0-6 by the former champion, who announced earlier this week that he would be retiring at the end of the tournament.

"Andy was playing I think really good at the net, coming into the net," Tomic told reporters. "Every time I wanted to pass him, he ended up hitting a half-volley winner or a volley winner.

"He was on top of me the whole match. I can't complain. The whole match was his way from start to finish pretty much."

Roddick's reward for beating Tomic is a third-round encounter with Italy's Fabio Fognini.
