Serena Williams unleashed her full arsenal to move almost effortlessly into the last 16 at Wimbledon with a crushing 6-2 6-0 win over Japanese veteran Kimiko Date-Krumm on Saturday.

Williams, considered an old-stager herself despite being 11 years younger than her opponent, never allowed 42-year-old Date-Krumm to gain a foothold in the match, crunching winners and firing down aces with her usual high levels of aggression.

The pedestrian Date-Krumm serve seemed to belong to a different era and was ruthlessly dispatched as Williams took the first set in 35 minutes, breaking three times.

The second set was an exercise in brutality as Williams wrapped up the match without dropping another game.

Williams, chasing a sixth Wimbledon title and 17th grand slam overall, will face Germany's 23rd seed Sabine Lisicki in the fourth round.

Elsewhere Laura Robson pulled off a heroic comeback against hard-hitting New Zealander Marina Erakovic to move into the fourth round at SW19 for the first time.

The British number one surrendered the first set in just 22 minutes, but she came back from a break down in the second to level and kept up her momentum to record a highly impressive 1-6 7-5 6-3 win on Court Two.

The victory means Robson becomes the first British woman to reach the last 16 at Wimbledon for 15 years.Having received words of encouragement from pop group One Direction and Prime Minister David Cameron this week, the spotlight was on Robson.

Pat Cash, Serena Williams and Virginia Wade had, inadvertently with their praise, added even more pressure on Robson by tipping her for greatness, and it looked for a long time like she was going to buckle after a disastrous first set.

But the 19-year-old responded brilliantly, discovering the power, movement and placement that had escaped her early on to claim victory and set up a fourth-round clash against Alison Riske or Kaia Kanepi.
