Top seed Ashleigh Barty powered into the third round of Cincinnati WTA tournament on Wednesday with a 6-4, 6-1 defeat of Maria Sharapova.
Australia's Barty, 23, won the battle of former number one players in just over 90 minutes.
The reigning Roland Garros champion beat five-time Grand Slam winner Sharapova, who was Cincinnati champion in 2011, for the second time this season after a win at the Australian Open.
It was Barty's 40th victory of 2019 and she goes on to face either Poland's Iga Swiatek or Anett Kontaveit of Estonia.
