Blake v. Santoro Goes the Distance [UPDATED]

fabricesantoro Blake v. Santoro Goes the Distance [UPDATED]Live from a very electric — and very stunned — Arthur Ashe Stadium, we've got an upset watch to alert. The absolutely stubborn and scrappy Fabrice Santoro of France has brought James Blake the distance. We're going to a fifth set.

Santoro has played agonizingly good defense and it's frustrating Blake to no end. Through four sets, Blake has made a whopping 55 unforced errors. James Blake has never won a fifth set in his career.

The 34-year-old Santoro has never done better than the quarterfinals at the Australian Open, but he has caused fits for some big names recently. Roger Federer needed two tie-breaks to beat him in Dubai last year and he played a memorable five-setter with Tomas Berdych at last year's Wimbledon.

We'll keep you updated through the Fifth, and, if there's an upset we'll be right here bringing you all post-match reaction.

UPDATE: James Blake has won 6-4, 3-6, 6-2, 4-6, 6-4. I'll have post-match reaction in moments.
