Andy Roddick's decision to take some risks paid off Friday as the American rallied to beat Spain's Rafael Nadal and book a clash with giant-killing Tomas Berdych in the final of the Miami ATP Masters 1000. Roddick engineered a turnaround to triumph 4-6, 6-3, 6-3 over world number four Nadal, who was the highest seed left in the draw. Berdych, who saved a match point en route to a stunning upset of world number one Roger Federer in the fourth round, dismantled fifth-seeded Swede Robin Soderling 6-2, 6-2. Berdych, who said he wanted to be "aggressive but with lots of control" was able to do just that. He broke Soderling four times and faced only one break point himself. After being pushed around in the first set by Nadal, who will still return to number three in the world on Monday, Roddick realized he would have to do more.
