Serena Williams showed no ill-effects from a late-night doubles outing, barely breaking sweat as she cruised through to the third round of Wimbledon with a 6-1 6-1 stroll against South African Chanelle Scheepers.
The American top seed was first up on Court One on Wednesday, having had to wait until 9pm on Tuesday to clinch a three-set win with sister Venus, but looked fresh and eager to make short work of 94-ranked Scheepers.
Having dropped only three games in the previous round, Serena was even more convincing as she overpowered Scheepers, sending down eight aces and hitting 26 winners as she wrapped up proceedings in only 49 minutes.
The world No.1, who went out at this stage at last month's French Open, faces either Petra Cetkovska of the Czech Republic or 25th-seeded Frenchwoman Alize Cornet.
