World number one Roger Federer held off the challenge of Argentine Jose Acasuso to reach the second round of the Cincinnati Masters — where he will be joined by fourth seed Novak Djokovic. The top-seeded Swiss went through 6-3 7-5 in one hour and 10 minutes to earn a clash with David Ferrer. Acasuso was broken in the eighth game, with Federer then serving out to take the opening set.
