Germany's 17th seed and 2016 U.S. Open champion Angelique Kerber moved into the second round with a 6-4 6-4 win over Australia's Ajla Tomljanovic at Louis Armstrong Stadium. Kerber, who was knocked out in the first round last year, converted all five break points in the match but she was tested in the second set when Tomljanovic saved a match point and came back from 2-5 down before the German served out the match.
