GSTAAD, Switzerland, July 8: Roger Federer to come down to earth after his weekend win at Wimbledon with a scratchy victory in his opening match at the Swiss Open on Tuesday.

A scrappy performance from Spanish qualifier Marc Lopez quickly showed the new Swiss success story that he was human after all.

But Federer survived to collect a 6-3, 6-7 (4/7), 6-3 result into the second round at this alpine valley village.

With the top seed leading 6-3, 5-4, Lopez rose to the occasion, saving a pair of match points to prevent the Helvetic hero from serving out a quick victory.

A double-fault from Federer combined with a cross-court wide opened the door for the outsider.

The contest went to a third set, lasting nearly another hour before Federer finally struggled home.

“I just served so badly, I have not confidence on this fast clay,” said the 21-year-old who leads the ATP in match victories, and holds five titles on four surfaces this season.

“But it was so important to come here and play. I had to come - for the fans, for the tournament and for Switzerland. But this match was a near-miss.”

Other seeds got through with a minimum of stress.

Number 2 German Rainer Schuettler, who played the Australian Open final against Andre Agassi six months ago, defeated Australian Wayne Arthurs 6-2, 6-3, while three-time champion Alex Corretja made a winning start.

The 29-year-old Spaniard is playing for the firsr time since the birth of his daughter nearly three weeks ago.
