The second-seeded Verdasco will attempt to become the first Spaniard to win a title in the Bay Area since Manuel Santana in 1964. Verdasco will meet the winner of a later match between top-seeded Andy Roddick and No. 7 Sam Querrey.
"I was not playing great in the first set but I wasn't missing," Verdasco said. "We were both up and down and when it came to end of the match I tried to push harder, make good returns and send the ball deep. I hit two good forehands and he made a couple of mistakes. He's playing well this year and he's dangerous."
