LONDON — Nicol David retained her World Series Squash Finals title Sunday with a straight games defeat of England's Laura Massaro, the player she had also defeated to clinch a seventh World Open last month. The 29-year-old Malaysian star won 11-3, 11-2, 11-9 having trailed 6-8 in the third game. “It means a lot to start 2013 with a good win. Knowing she was in front of her home fans I knew I had to start strongly and not let her feed off the crowd,” said David after the final played at London's Queen's Club. In the men's final, Egypt's Amr Shabana came from behind to beat England's Nick Matthew 4-11, 11-2, 11-4, 11-6. — AP
