Serena Williams sends ominous warning to her Wimbledon rivals

It was business as usual for Serena Williams as she went back to the day job and surged into the Wimbledon quarter-finals.

Andy Murray's doubles partner is a pretty handy singles player too, as demonstrated by a dominant victory over Carla Suarez Navarro.

Williams, who delighted Centre Court alongside Murray on Saturday evening, moved ominously closer to an eighth Wimbledon title with a 6-2 6-2 win.

The 37-year-old, sporting a child's plaster on her left elbow, never looked like coming unstuck against the world number 31.

Two breaks of serve gave her the first set in just 31 minutes, the highlight a stunning flicked backhand across the helpless Suarez Navarro.

Williams also looked more confident at the net than in her previous matches, so maybe the Murray link-up is paying off.

Two more breaks at the start of the second put Williams in total control, although Suarez Navarro did at least lay a glove on her with a surprise break to love.

It was only a temporary blip, as Williams broke back before serving out the match to set up a meeting with fellow American Alison Riske, who knocked out world number one and top seed Ashleigh Barty, in the last eight.
