Yes it did happen. For those of us who are old enough it started with Michael Chang in the late 80's and culminated with Jim Courier's back to back titles in the early '90's. Let's not forget that Andre made two finals appearances at the French during that time too. It was brief but it can happen. The problem is that it took some of the most talented and hard-working players of their generation to pull it off. Chang, Agassi and Courier were never masters of clay. But they learned enough about the surface to win. Chang and Courier were decent at sliding on the clay and Agassi was simply talented enough to take the ball on the rise and inflict a hardcourt game on clay. My point being, the US produces talented players but for today's international game you have to start training on clay early on. And, it has to be european red clay. The green har-tru courts just don't play the same. I'm going to hold out hope that we'll see another talented american generation in my lifetime make an impact like those three did.
