Kim Clijsters was returned to the WTA Tour after 7 years at the Dubai Tennis Championships.
Muguruza, runner-up at the recent Australian Open, defeated Kim 6-2 7-6 (8-6) in one hour and 37 minutes on Monday. Playing her first match since losing to Laura Robson in the second round of the US Open in August 2012, the Belgian was rusty at times as she racked up 10 double faults and gave up 15 break points.
However, Clijsters’ fight and impressive groundstrokes in the second set would have given her plenty of hope for the months ahead.
