Serena Williams re-established her customary superiority, hammering Daria Gavrilova 6-1, 6-2 to reach the second round of the Cincinnati Masters on Monday. The 23-time Grand Slam champion showed full recovery in her first match since suffering the worst defeat of her career two weeks ago in San Jose when she was crushed 6-1, 6-0 in 51 minutes by British No. 1 Johanna Konta. But the 36-year-old was all business Monday as she cleaned up on Australian Gavrilova, with Williams winning an 11th straight match here. Though she has not played the tournament in three years, Williams lifted back-to-back titles in 2014 and 2015 after losing the 2013 final to Victoria Azarenka. Andy Murray's injury comeback was sidetracked as the three-time Grand Slam champion lost 6-1, 1-6, 6-4 to Lucas Pouille.

Murray, returning from January hip surgery, was unable to get past the French 16th seed, hampering his preparations for the US Open starting on August 27 "Physically, I felt okay. It's quick conditions here," Murray said. "He was a little bit sharper than me out there. "I maybe wasn't reacting as quickly to some shots I would have liked. Murray last played 11 days ago in a Washington third-round match which took him three hours to win and ended at 3 a.m. The 31-year-old two-time Wimbledon winner is working his way back slowly and felt he could not subject his body to a quarter-final just over 12 hours later, prompting him to withdraw from that event.
