US Open 2017: Maria Sharapova defeats Timea Babos to sail into third round; Zverev, Kyrgios crash out

Former world number one Maria Sharapova continued to impress on her comeback after notching up an impressive win over Hungary's 59th ranked Timea Babos in the second round of the women's singles at the US Open on Wednesday. However, they were two big upsets in the men's singles with next-generation rising stars Alexander Zverev and Nick Kyrgios sent crashing out of the tournament. 

Sharapova, who downed second-ranked Simona Halep in her first Grand Slam match after a 15-month doping ban, defeated her hungarian opponent in straight sets 6-7 (4/7), 6-4, 6-1 .  "I felt like going into the match I just wanted to get it done," Sharapova said. The 30-year-old Russian became the first player into the third round where she will face Russian-born US teen wildcard Sofia Kenin. "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."

Sharapova, whose five Grand Slam titles include the 2006 US Open, tested positive for meldonium at the 2016 Australian Open, her most recent Grand Slam appearance until this week. "Every day I have the chance I have to play out here at the US Open is a special day and I'll look forward to the next one," Sharapova said.

German fourth seed Zverev, whose has notched up five ATP titles this year include a win over Roger Federer in this month's Montreal final, was knockout out of the tournament by 61st-ranked Croatian Borna Coric 3-6, 7-5, 7-6 (7/1), 7-6 (7/4).  "He had a most unbelievable year where he won basically everything," Coric said. "It does mean a lot to me to win this match."

Coric, who next faces South African Kevin Anderson for a spot in the last 16, was one point from being pushed to a fifth set before winning five in a row to take the 12th game of the final set.

Australia's 14th seed big hitting Nick Kyrgios, hurt his right shoulder in a 6-3, 1-6, 6-4, 6-1 first-round loss to fellow Australian John Millman."Early in the third set I hit one serve and I never felt the same after that," Kyrgios said. "Something didn't feel right in my arm."Kyrgios, 22, beat Rafael Nadal two weeks ago on the way to the biggest final of his career at the ATP Cincinnati Masters before falling to Grigor Dimitrov.
