DAY 5 of the Brisbane International saw only three Round of 16 matches play out, with three Americans taking on their respective opposition. The USA had a successful day on court with all three proceeding to the quarter finals in straight sets.

Australian Sam Stosur stunned former number one Angelique Kerber in the first round of the competition before taking on eighth seed Madison Keys in Round 2. Stosur got off to a solid start against the American in front of a hostile home crowd before a tiebreaker saw Keys win the first set, with the pair fairly well matched and unable to be separated early. Both players used their powerful serve to take control, with Keys making it clear in the second set that she will fight for her chance to remain in the tournament. While Stosur did not play poorly against the eighth seed, she was well and truly outplayed in the second set, eventually going down 5-7 3-6.

Czech, Barbora Strycova could not continue her strong start to the tournament, falling to Alison Riske in straight sets, 3-6 4-6. Riske was clinical, winning 70 per cent of her first serve points and capitalising off Strycova’s errors. Meanwhile, American Danielle Collins was just too good against Kazakh Yulia Putintseva, collecting a second straight sets win in three days and only dropping one game for the entire match, 6-1 6-0 – meaning she has only dropped three games throughout the tournament so far and not one set. That being said, Putintseva put up an impressive fight on her fifth consecutive day on court, having played three days of qualifiers prior to joining the main group.
