 Roddick is chasing his 23rd ATP tour title |
Top seed Andy Roddick won the battle of the big servers as he beat Ivo Karlovic to reach the final of the Legg Mason Classic in Washington on Saturday. Roddick fired 11 aces as he beat the 6ft 10in Croatian 7-6 (9-7) 7-6 (7-5).
"I was lucky," Roddick said. "You just try to get something in the tie-breakers against him. It's a coin flip - it flipped for me twice."
In the final Roddick will play 6ft 9in compatriot John Isner, who beat Gael Monfils 6-7 (4-7) 7-6 (7-1) 7-6 (7-2).
