US Open: Sharapova wins, Zverev, Kyrgios crash out

Sharapova, who downed second-ranked Simona Halep in her first Grand Slam match after a 15-month doping ban, defeated Hungary's 59th-ranked Timea Babos 6-7 (4/7), 6-4, 6-1 at Arthur Ashe Stadium.

"I felt like going into the match I just wanted to get it done," Sharapova said.

"It wasn't my best tennis. It was scrappy tennis but sometimes those kind of matches are a lot of fun and this was one of those days."

The 30-year-old Russian became the first player into the third round where she will face Russian-born US teen wildcard Sofia Kenin.
