Untroubled Serena into Wimbledon quarter-finals

London - Seven-time Wimbledon champion Serena Williams coasted into the quarter-finals on Monday beating Spaniard Carla Suarez Navarro 6-2, 6-2.

The path for the 37-year-old American of equalling Margaret Court's all-time record of 24 Grand Slam titles appears significantly easier.

Her quarter-final opponent on Tuesday will be Alison Riske who knocked out world number one Ashleigh Barty earlier on Monday.
