| French Open champion Barty double faulted to 
				give Sharapova a 2-1 lead in the first set and it looked like an 
				upset could be brewing in the showdown between the two former 
				world number ones.
 But an error-prone Sharapova bowed out after she produced six 
				double faults and squandered six of her seven break point 
				opportunities.
 
 "Overall it was a pretty clean performance," Barty said.
 
 "It's difficult to come out against a player like Maria. She's 
				an incredible champion, she knows how to fight and she makes you 
				earn every single point.
 
 "So I was really pleased with the way I was able to hang in 
				there today and win some of those big points."
 
 Barty earned an early break in the second set when she rifled a 
				crosscourt forehand that caught Sharapova flat footed for a 2-0 
				lead.
 
 Sharapova fought hard the next game, forcing seven deuces but 
				was unable to break and Barty cruised to the finish from there, 
				winning 11 of the last 13 games.
 
 Barty will next face Anett Kontaveit, who defeated Polish 
				teenager Iga Swiatek in straight sets.
 
 Wimbledon champion Halep had her back against the wall against 
				the big-serving Alexandrova when she dropped the first set and 
				trailed 5-4 in the second but won the next three games and 
				elevated her play again in the decider.
 
 The match was the first for Halep since she pulled out of her 
				quarter-final at the Rogers Cup on Friday with an Achilles issue 
				but she moved well in her battle with the Russian.
 
 Fourth seed Halep is searching for her first title at the event 
				after three runner-up finishes in 2015, 2017 and 2018.
 
 "I feel confident every time I come here but the conditions are 
				very tough. The court is very fast," the Romanian said.
 
 World number one Naomi Osaka improved to 4-0 lifetime against 
				Aliaksandra Sasnovich with a 7-6(3) 2-6 6-2 win.
 
 Osaka, who regained the top ranking after Barty's early exit 
				from the Rogers Cup last week, smacked 24 winners as she looks 
				to sharpen her game before heading to New York later this month 
				to defend her U.S. Open title.
 
 She faces Hsieh Su-Wei in the third round.
 
 Third seeded Karolina Pliskova crushed lucky loser Wang Yafan 
				6-1 6-3 and Donna Vekic knocked out former champion Victoria 
				Azarenka 6-2 7-5 to set up a showdown with Venus Williams on 
				Thursday.
 
 Seventh seed Elina Svitolina, ninth seed Aryna Sabalenka and 
				big-serving American Madison Keys all advanced to the third 
				round behind straight set wins.
 
 Svitolina set up a date with American Sofia Kenin, who beat 
				Zarina Diyas 6-4 6-1.
 
 Another American, eighth seed Sloane Stephens, had a tougher 
				match against Yulia Putintseva but prevailed 2-6 6-4 6-3 and 
				will next face Russian Svetlana Kuznetsova, a 4-6 7-6(7) 6-2 
				winner over Ukraine's Dayana Yastremska.
