Crawford stuns Bencic at the Brisbane International

World number 142 Samantha Crawford booked her spot in the quarter finals of the Brisbane International when she pulled off the shock result of Wednesday with a stunning 7-5, 7-5 win over seventh seed Belinda Bencic.

The win was the 20-year-old American's first top 20 scalp. Whilst Crawford was magnificent, Bencic had a poor day in the office as her forehand really let her down. The Swiss player saved five match points but was unable to take the match into a third set. 

Victoria Azarenka, the two-time Australian Open champion, reached the quarter finals with a 6-3, 6-2 win over Belgium's Ysaline Bonaventure.

Angelique Kerber took just 62 minutes to thrash American Madison Brengle 6-3, 6-0 to set up a quarter final clash with Russia’s Anastasia Pavlyuchenkova.

Kerber's doubles partner, Andrea Petkovic, eliminated Ekaterina Makarova 7-5, 6-4.

In the final match of the day Garbine Muguruza was forced to retire after she hurt her foot during her battle with Varvara Lepchenko. The Spaniard received treatment at the completion of the lengthy first set. She returned for one game in the second set before conceding the match with the score at 6-7, 0-1.
