Cincinnati

Cincinnati:After a wild week in Montreal and Toronto, who knows what will happen in Cincinnati. Keothavong defeated Italy’s Alberta Brianti in round one of Cincinnati qualifying but then retired when 5-7 7-6 4-1 down to Greek Eleni Daniilidou.

What a match it figures to be. Del Potro has won their past two head-to-heads, including an outstanding 2009 U.S. Open final, and winning three in a row wouldn’t help Federer’s confidence heading into Flushing Meadows. Both were faring better back then.

The top seeds here are also the top players in the world — Novak Djokovic, Rafael Nadal, Federer and Andy Murray. Federer titled here for a fourth time by edging out American Mardy Fish in last year’s final. Djokovic was the runner-up here in 2008 and 2009. Murray beat Djokovic in the ’08 Cincy final.
