4 hours and still going strong. Both men had the physio on (for cramps?). Safin broken 3 times in a row in the final set and Mantilla serving for the match broken each time in return and the game now stopped for light. Safin seems absolutely nerveless. Surely this is the finest match in the FO so far. Safin has played exquisitely at times and just plain overhit at other times. Still you can't watch and hope he wins. Some of his attacking play has just been glorious. Oh but for a forehand volley to match the rest of his game today. No passion/desire? Both these guys want it bad. Not bashing Roddick here after all he went 5 sets with El-Aynoui at the AO but the difference between these two men and Roddick is clear to see. For whatever reason, Roddick just didn't want it as bad. Hopefully that will change in the future. Men's tennis needs ALL it's superstars playing at their best and trying their hardest at the slams.
