| Osaka fired 16 aces and broke her Greek 
				opponent four times in the two hour, seven minutes encounter, 
				but struggled in the second set tiebreak when Sakkari won five 
				points in a row before squaring the match on an unforced error 
				from the Japanese.
 The pair traded breaks in the opening stages of the final set 
				before former world number one Osaka clinched victory, despite 
				double faulting on her first match point.
 
 "I knew going into it that it was going to be a really hard 
				match," world number four Osaka said. "I think in the second set 
				I was just complaining a lot in the tiebreak. I was just trying 
				to calm down and stay positive."
 
 Former U.S. Open champion Sloane Stephens, 24th in the WTA 
				rankings, fell at the first hurdle to Liudmila Samsonova, who is 
				ranked more than 100 places below her. The 129th ranked Russian 
				won 6-4 2-6 6-3.
 
 Samsonova next faces former Wimbledon champion Petra Kvitova who 
				overcame a slow start and reeled off 12 of the last 13 games to 
				down another Russian in Anastasia Pavlyuchenkova 2-6 6-1 6-0.
 
 Wildcard Maria Sharapova, playing her first match since losing 
				in the first round of last year's U.S. Open, was beaten 3-6 6-1 
				7-6(3) by Jennifer Brady.
 
 The American qualifier will take on world number one Ash Barty 
				in the second round.
 
 Eighth seed Madison Keys advanced with a 6-3 6-2 win over the 
				Czech Republic's Marie Bouzkova.
