AUSTRALIAN OPEN: DAY 5
 Sloane Stephens defeated  Petra Martic (CRO) 7-6(6), 7-6(5).
 Danielle Collins defeated  Caroline Garcia (FRA) 6-3, 6-2.
 Amanda Anisimova defeated  Aryna Sabalenka (BLR) 6-3, 6-2.
Christian/Muhammad (USA) defeated Aoyama/Marozava 7-5, 7-5.
 Bryan/Bryan (USA) defeated Mannarino/Mies 7-5, 4-6, 6-2.
 Frances Tiafoe defeated  Andreas Seppi (ITA) in five sets: 6-7(3), 6-3, 4-6, 6-4, 6-3. With this victory, Tiafoe is into the fourth round for the first time at a major.
 Taylor Fritz lost to  Roger Federer (SUI) 2-6, 5-7, 2-6.
McDonald/Sandgren lost to Chardy/Martin (FRA) 4-6, 4-6.
The sole American male player left in the draw is none other than the twenty-year old Tiafoe. Next up for him is  Grigor Dimitrov (BUL). Dimitrov won their only previous encounter last year in three sets, two of which were tiebreak sets; however, the American won the second set 6-3. Can he get some revenge this match and keep alive his hopes of perhaps winning his first major?
MORE SEEDS FELL
 Caroline Wozniacki (DEN) lost to  Maria Sharapova (RUS) in three sets: 4-6, 6-4, 3-6. Wozniacki had a chance to win this in straight sets, she had the break in the first set; however, she could not hold on to the lead. She was the defending champion and her ranking will drop as a result of this early loss.
 Karen Khachanov (RUS) lost to  Roberto Bautista Agut (ESP) 4-6, 5-7, 4-6.
 Stefanos Tsitsipas (GRE) defeated  Nikoloz Basilashvili (GEO) 6-3, 3-6, 7-6(7), 6-4.
 Diego Schwartzman (ARG) lost to the returning Czech,  Tomas Berdych. Berdych dropped the first set and then came roaring back to win 5-7, 6-3, 7-5, 6-4. Next up is a familiar opponent, Rafael Nadal.
