The ATP Houston, also known as the Fayez Sarofim & Co US Men’s Clay Court Championship, is the only clay court tournament still played in America. However, despite the fact that clay seems the America’s least favourite surface, Americans have an excellent record in the event. Since the turn of the Millennium, they have won 8 of the 15 renewals, and provided a further 8 runner-ups. However, this is not an event that has been dominated by one or two Americans and, though Andy Roddick has won 3 titles, there have been 6 different winners, which comprise Andre Agassi, Andy Roddick, Mardy Fish, Ryan Sweeting, John Isner and Jack Sock. Isner and Sock are prominent in this year’s betting, and it’s time to take a look at some of the leading protagonists.
