<p> The world number one will face either Roger Federer or Novak Djokovic in Sunday's showpiece. <br /><br />There was nothing to separate the players in an enthralling first set in which both were rock solid on serve but Nadal edged the tiebreak to move ahead. <br /><br />From 2-3 down in the second set Murray found another gear and reeled off five consecutive games and appeared to be heading for a stunning victory before Nadal roared back. <br /><br />Nadal seized on a Murray lapse in the decider to break in the third game and had a match point when Murray served at 3-5, only to be stretched into another nerve-wracking tiebreak. <br /><br />Murray made the better start and forged into a 4-1 lead but his relentless Spanish opponent recovered and stormed into a 6-5 lead. Murray again saved a match point but when a third opportunity arrived, Nadal sealed victory with a forehand. <br /><br />On Friday, India’s Mahesh Bhupathi and Max Mirnyi of Belarus clinched the last doubles semifinal spot after defeating South Africa’s Wesley Moodie and Swede Dick Norman 6-4, 6-4. The two finished runners-up in Group B with their victory on Friday, and will now face Group A winners, Poland’s Mariusz Fyrstenberg and Marcin Matkowski. <br /><br />“It is nice being in the semifinals,” said Bhupathi. “Going into the match it was a must-win situation for us, so we were glad to get it done. We played pretty well, very solid. I thought we served really well and happy that we won.”<br /><br />This is the first time Bhupathi and Mirnyi have entered the semifinals in the three times they have take part in the tournament. They had failed to clear the round-robin stages on their first two appearances in 2003 and 2004 in Houston.<br /><br />Meanwhile in the first doubles semifinal on Saturday, Daniel Nestor of Canada and Nenad Zimonjic of Serbia scored a hard-fought 6-3, 3-6, 12-10 over defending champions Mike Bryan and Bob Bryan.<br /></p>
