Agnieszka Radwanska progresses in Toyko

Agnieszka Radwanska had little trouble in booking her place in round two of the Toray Pan Pacific Open as she overcame Coco Vandeweghe 6-3 6-3 on Monday.

Radwanska has fond memories of the tournament in Tokyo, having won the competiton in 2011 and finishing runner-up to Nadia Petrova a year later.

And the Pole – seeded seventh – had little trouble against her American opponent in their first-round tie, coming through in a little over 90 minutes.

There were three breaks of serve in the opening four games of the first set, but from there Vandeweghe failed to make any further inroads as Radwanska saw out the opener.

It was a similar story in the second set with three breaks in the opening five games, and Radwanska rounded off success on her first match point by breaking Vandeweghe again in game nine.

Camila Giorgi also progressed to round two thanks to a come-from-behind 4-6 7-6 (7-3) 6-3 victory over Caroline Garcia.

Garcia was 3-0 up in the second set, but was unable to press home her strong position.

Barbora Strycova was a 7-5 6-2 victor over Naomi Osaka.
