Swiss world number one Roger Federer advanced into the third round at the Madrid Masters on Tuesday (Oct 17th) after beating the combative Chilean Nicolas Massu 6-3, 6-2.

Fourth seed David Nalbandian fought his way back from 5-2 down in the third set to beat off a determined challenge from French qualifier Julien Benneteau, winning through 6-7, 6-2, 7-5.

The Argentine faces an third round clash against former British number one Tim Henman who upset Spanish 14th seed David Ferrer 6-1,4-6, 6-1.

Former winner Marat Safin overcame resistance from Jose Acasusoof Argentina to win 7-6, 6-7, 6-3, setting up a meeting with Marcos Baghdatis of Cyprus in the second round.

Massu, who reached the Madrid final in 2003 but is unseeded this year, played some fine aggressive tennis in the opening set against Federer, but the top seed soon found his rhythm.

The Swiss broke once in the first set and twice in the second to extend his winning streak to 15 matches.

He will play the winner of the match between Spain's former number one Juan Carlos Ferrero and Robin Soderling of Sweden in the third round.

Sixth seed Andy Roddick took full advantage of his powerful serve to see off Frenchman Sebastien Grosjean 6-4, 7-6.

Spain's Tommy Robredo, who captured the biggest title of his career when he won the Hamburg Masters in May, also progressed after a gritty 7-6, 7-6 win.

Frenchman Gael Monfils had to retire after straining an ankle when he leapt into the air while a set up in his first round match against Slovak Dominik Hrbaty and brought a premature end to his season.
