Tomic fined US$10k for lewd comments
Bernard Tomic was sent packing early at the US Open and his minimal earnings were offset by a US$10,000 (S$13, 590) fine for a crude on-court outburst he directed at a heckler during his first-round loss.
The Australian was caught on camera directing a number of sexually explicit comments towards someone in the crowd.
Tomic, who later apologised, will receive US$43,313 for his first-round appearance.
Wawrinka battles to win in straight sets
Two-time Grand Slam winner Stan Wawrinka rallied from 5-2 down in the second set to clinch victory over Alessandro Giannessi on Thursday and reach the third round of the US Open.
After dominating the opening set, the Swiss battled back to force a tie-break and then broke the Italian in the final game of the match to finish with a 6-1, 7-6 (7-4), 7-5 victory.
"I was trying to be a little more aggressive," said Wawrinka, who blasted 57 winners, including 26 off his forehand. "I'm very happy the way I won the match."
Del Potro hands warning to the field
Wildcard Juan Martin del Potro showed himself a force to be reckoned with at Flushing Meadows as the Argentinian swept aside American Steve Johnson 7-6 (7-5), 6-3, 6-2 to reach the third round of the US Open on Thursday.
Del Potro, who won the 2009 US Open in a thrilling five-setter over Roger Federer, has come through a long battle with a wrist injury that has dropped him to No. 142 in the rankings.
"I'm so happy to be playing tennis again after my third surgery on the wrist and I think I did a really good job to come back at tennis," he said.
