DAY 2: AMERICAN RESULTS
 Serena Williams (USA) defeated Belinda Bencic (SUI) 6-4, 6-3. It started off shaky and got better in the middle; however, she stumbled across the finish line. Nevertheless, this is a positive for Serena, who traditionally struggles in round one of the Majors. Given that this opponent had beaten her the last time they met, it was indeed a good victory for her. Unfortunately, her draw just gets tougher, next up is the always dangerous Lucie Safarova and she has the weapons to make life very uncomfortable for the American down under.
Reilly Opelka (USA) lost to  David Goffin (BEL) 4-6, 6-4, 2-6, 6-4, 4-6. Opelka had chances to close this out with the victory but just could not convert on his break point opportunities late in the match.
Jared Donaldson (USA) lost to Rogerio Dutra Silva (BRA) 6-3, 6-0, 1-6, 4-6, 4-6

 Alexander Zverev (GER) comes back from a 2:1 deficit down under to defeat Robin Haase 6-2, 3-6, 5-7, 6-3, 6-2. He did not wilt in the heat, nor cave under the determined attack of Haase. This was a good effort from our spotlight player and it is a positive sign that he is continuing to mature.
