Roger Federer survived the threat of a huge upset to beat Spain's Feliciano Lopez and reach the quarter-finals of the US Open.
The three-time defending champion was in trouble as Lopez's big serving and sharp volleys gave him the first set.
But Federer battled through a close second set by breaking in game 10 and then found his best form to race to victory.
The world number one goes on to face Andy Roddick in the QF in a repeat of last year's final.
"(Lopez) was playing fantastic for the first two sets, dictating play, serving unbelievable," said Federer.
"When you do lose a set you start to wonder, 'Maybe this is the night it's not going to work out for me'. But I played great at the end."
