Caroline Wozniacki moved into the Australian Open quarterfinals with a 6-3, 6-4 win over Anastasija Sevastova on Sunday and is now just one win from ensuring she'll retain the No. 1 ranking.
The 20-year-old Dane, playing her first major with the No. 1 ranking, finished off Sevastova with a powerful forehand winner in 1 hour, 20 minutes to advance to the quarterfinals at Melbourne Park for the first time. She'll keep her top ranking just by reaching the semifinals.
She wants more than that though: a first Grand Slam title.
