Sizzling Serena joins sister and Wawrinka in Australian Open fourth round
Williams sisters inspire each other as Swiss defending champion cruises on

World number one Serena Williams took time to wake up before sizzling into the Australian Open fourth round on Saturday, joining resurgent sister Venus and men’s defending champion Stan Wawrinka.
The American top seed, vying for a sixth Australian title and the first since 2010, was slow to get in the groove against 26th-ranked Ukrainian Elina Svitolina, going down 6-4 in the first set.
But she shook off the cobwebs under the blazing sun on Rod Laver Arena to rattle through the next two sets 6-2, 6-0.
It keeps alive her quest to add a 19th grand slam title, which would take her to clear second on the all-time Open Era Grand Slam winners list.
She currently has 18 alongside Chris Evert and Martina Navratilova and is four behind German great Steffi Graf’s 22.
