Top seeds though in Cincinnati

The top six seeds all safely progressed through to the third round at the Cincinnati Masters to keep their US Open preparations on track.

Eight of the world's top 10 players are in Ohio ahead of the final grand slam of the year, which starts at Flushing Meadows on August 30, and world number one Rafael Nadal led a good day for the more-fancied names with a comfortable 6-2 7-5 win over American qualifier Taylor Dent.
