Caroline Wozniacki has sealed a 7-5 6-0 victory over Christina McHale to book a place in the third round of the Madrid Open.
The fifth seed had a stuttered start to the first set by losing her opening service game, but she eventually responded with a break of her own.
McHale kept Wozniacki on her toes by breaking back, but the Dane was able to recover to snatch two further break points and claim a one-set lead.
The second set was a breeze for Wozniacki as she went two breaks up swiftly, and McHale lost her intensity from the first set.
