US Open 2017: Sharapova trounces Kenin to storm into last 16, Schwartzman upsets Cilic

2006 US Open winner Maria Sharapova stormed into the fourth round at the US Open by trouncing US teen Sofia Kenin on Friday. However, there was another casualty in the men's section with 2014 champion Marin Cilic crashing out of the tournament.

Former world number one Sharapova, 12the 2006 US Open winner in her first Grand Slam since serving a 15-month doping ban, downed the 139th-ranked wildcard 7-5, 6-2 and moved into a fourth-round clash with Latvian 16th seed Anastasija Sevastova.

Five-time Grand Slam champion Sharapova, who tested positive for the blood booster meldonium at the 2016 Australian Open, reached the round of 16 for the 14th time in 15 Slams since the 2011 US Open.

It was the end of the campaign for Croatia's fifth seed Cilic, who was eliminated 4-6, 7-5, 7-5, 6-4 by Argentine 29th seed Diego Schwartzman. "(The injury) played a quite significant part, and just being injured and not being able to keep that good form," Cilic said. 

Cilic's exit ensured a first-time Slam finalist will come from his draw half, which now lacks a top-10 player and has only one Slam semi-finalist, American Sam Querrey, who made it in July at Wimbledon. "Everyone is improving," Cilic said. "And you have a lot of youngsters coming up that are playing better."
