Andy Murray clinched the No. 2 world ranking in men’s tennis despite struggling with his serve in Saturday’s semifinal victory over Jo-Wilfried Tsonga at the Montreal Masters. The British third seed won 6-4 7-6 (10-8) in the Canadian hardcourt event to overtake Rafael Nadal and set up a final clash with either American fifth seed Andy Roddick or sixth-seeded Argentine Juan Martin Del Potro.
