Unsatisfied with blasting lightning-like serves past her baffled and befuddled opponents, and dropping only 16 games in five matches at the US Open, Serena Williams warns she is about to get serious.
The 14-time Grand Slam champion, a three-time US Open winner coming off a Wimbledon title in July and London Olympic gold last month, meets Italian 10th seed Sara Errani on Friday to decide a berth in Saturday's US Open final.
"I feel like I'm going to get more focused and serious and start playing 'Serena tennis' in the next couple of rounds," Williams said.
