The second-seeded Almagro fired 17 aces en route to his seventh career title and second in the last three weeks after stunning crowd favorite Robin Soderling in the final at the Swedish Open.

"Due to fatigue and a sprained ankle in Atlanta, I am not in good shape to play," Fish said. "I need to rest in order to compete at a high level." Fish has won his last 10 matches, including two titles in his last two events.
