Defending champion Coco Gauff roars past Tatjana Maria into US Open third round

Defending champion Coco Gauff cleaned up early mistakes to beat unseeded German Tatjana Maria 6-4 6-0 in a lopsided second round meeting at the U.S. Open on Wednesday. The American beat Maria in Auckland last year and she held on to the blueprint, roaring back from an error-riddled first set to sweep through the second and close out the affair with a sublime backhand winner.
