The first six games Roger Federer served Monday at the French Open, he won each at love. In other words, he won a perfect 24-of-24 points on his serve to open the match. Yet, Federer lost the first set. He could not break the serve of his opponent, Tommy Haas, and Haas prevailed in the first-set tie-breaker. Ultimately, Federer prevailed, 6-7, 5-7, 6-4, 6-0, 6-2.
