Notes: Weak, weak seeded line-up; tough openers include (1) Davydenko vs. Safin, (4) Andreev vs. Ginepri, (6) Tipsarevic vs. Crazi Dani, and (5) Cuevas vs. Lu (upset alert); Russians have won 13 titles in the 19 years of the event; unseeded Igor Kunitsyn is the defending champ, and is looking at a second-round meeting with the Davydenko-Safin winner; Davydenko looking for fourth Moscow title; Yevgeny Kafelnikov won the Moscow title five years in a row from 1997-2001.

Sean Randall breaks down what was a crazy day of upsets at the US Open Saturday.

Things will be heating up at the US Open this weekend with a some great matchups.

In the highlight match of the evening, Andy Roddick became the 36th player in the Open Era to reach 500 career match victories.

Andy Roddick reached 500 while Roger Federer boarded a flight from Switzerland to Montreal.

Seeds: Andy Roddick, Juan Martin Del Potro, Jo-Wilfried Tsonga, Fernando Gonzalez, Robin Soderling, Marin Cilic, Tommy Robredo, Tomas Berdych, Mardy Fish, Tommy Haas, Ivo Karlovic, Viktor Troicki, Igor Andreev, Dmitry Tursunov, Dudi Sela, Sam Querrey

This year, Alexandra Stevenson, Vince Spadea, Travis Parrott, Phillip King, Nick Monroe, Ryan Sweeting, Donald Young have indicated they would be playing. Tommy Haas, Taylor Dent, the Bryan Brothers and Marcos Baghdatis have all been invited. Last year Tommy Haas came to the event, but did not play due to issues with the ATP, issues that have supposedly been worked out.

Roddick will face Roger Federer in their third meeting in the Wimbledon final. Federer was flawless in dismissing a determined former No. 2-ranked Tommy Haas 7-6(3), 7-5, 6-3. It was another solid performance from Haas who has shown he can play the former world No. 1 close, but perhaps doesn’t have the deep-down belief he can beat the Swiss. Last month Haas led Federer by two sets to love before losing in five at the French Open.

Andy Roddick is back after reaching his first Slam final since the 2006 US Open.
