NEW YORK (Reuters) - World number two Aryna Sabalenka sent Slovenian Tamara Zidansek packing in just under an hour on Wednesday, rolling through to the third round of the U.S. Open with a 6-3 6-1 win.

The Belarusian broke her opponent in the first game and never ceded the momentum as Zidansek struggled with her serve, committing four double faults, and making 19 unforced errors.
