Reuters, The Associated PressPublished: March 2, 2007 TENNIS The defending champion James Blake was handed a quarter-final berth at the Las Vegas Open after the ATP reversed a quirk in the rules of its new round-robin format that had seen him ousted in bizarre fashion. Needing to beat the Argentine Juan Martín del Potro on Thursday with the loss of no more than five games to advance to the quarter-final, Blake, the top seed, was leading, 6-1, 3-1, when his opponent retired because of breathing problems, handing the American a walkover. However, Blake was then told he would not advance as the rules said that games won or lost in a walkover did not count. His place would go to Evgeny Korolev on a head-to-head basis after the Russian beat Blake earlier in the competition. After lengthy discussions, however, the ATP backtracked and awarded Blake a place in the final eight. (Reuters) Safin and Hewitt have spoken out and are furious. Korolev has learned his first lesson about how the ATP works. Blake thinks it's fair. Who here thinks they did the right/wrong thing?
