Feliciano Lopez vs. Andy Murray (first night match, Ashe): Which Murray will show up? Well, we know Judy Murray will be there cheering on her son while drooling over "Deliciano's" chiseled good looks. This is a rematch from Wimbledon, where Murray had to spend days answering for his mother's very public crush. So come for the awkwardness, stay for the tennis. The Spaniard's big lefty serve suits the hardcourts, and if Murray comes out heavy-legged as he did in the second round against Robin Haase, he'll be in trouble.
Sabine Lisicki vs. Vera Zvonareva (second night match, Ashe): Lisicki's game is better than her ranking at the moment (No. 18 in the world), and if not for Serena Williams, the German, seeded 22nd, would be the one tagged as the player most likely to ruin a top seed's week. The two clashed earlier this summer in San Diego, with Zvonareva winning a gruelling three-setter. I expect another physical match contrasting Boom Boom's power vs. Vera's experience.
Juan Martin del Potro vs. Gilles Simon (second match, Armstrong): Pure power vs. pure counterpunching. Their games can match up perfectly. Watching DelPo fire away while Simon scrambles should make for a highly entertaining match. Don't be surprised if this one goes five sets, with both men struggling to stay on their feet. Get the ice bath ready, gentlemen.
Donald Young vs. Juan Ignacio Chela (second match, Grandstand):
