After the match in an on-court interview, Djokovic lambasted Roddick for joking that the Serb was suffering from 16 injuries, drawing boos from the US Open crowd.

We are going to learn a lot about Novak Djokovic tonight. And I think Novak’s going to learn a lot about himself when under the lights, in primetime the Serb challenges American favorite Andy Roddick for a spot in the US Open semifinals.

Dinara Safina, the No. 7-ranked player in the world who can leap all the way to No. 1 with a US Open win, was the other quarterfinal winner Wednesday, topping Flavia Pennetta 6-2, 6-3. The 22-year-old Russian, who earlier in the week was literally crying to her coach on a practice court regarding her exhaustion following a long summer and the Beijing Olympics, has gathered herself in time for the semifinal and a date with Serena Williams.

Wow a great afternoon of tennis yesterday with Roger Federer and Novak Djokovic each being stretched to the limit in five set wins.

Andy Roddick is suddenly looking all the wiser with the combination of skipping the Beijing Olympics and bring Patrick McEnroe on as a temporary coach. Gonzalez looked like he had the Beijing flu on Tuesday night, with barely enough energy to put up a fight.

Roger Federer hasn’t won four matches at a hardcourt tournament since the Australian Open. With three wins under his belt, Federer today tries for No. 4 against the heavy-hitting Igor Andreev.

We have a pretty nice line-up in store at the US Open on this Labor Day Monday in the U.S. Week two opens with Gael Monfils v. Mardy Fish followed by Rafael Nadal and Sam Querrey.

My new favorite women’s player, Jelena Jankovic, is already through today at the US Open. The Serb drama queen is the first player into the quarterfinals, and as long as she doesn’t win the title in NY I’ll be rooting for her and her quest to finish the year No. 1 without reaching the Slam final.
