Santos shines early on
Wayne Rooney and Ryan Giggs were among the watching Manchester United players as Justin Rose chased down Ricardo Santos at the Qatar Masters.
World number four Rose, runner-up to Jamie Donaldson in Abu Dhabi on Sunday, turned in a two-under 34, but that was five behind Santos, winner of the Madeira Islands Open last season.
The Old Trafford players flew to the Middle East for some winter sunshine training following their draw with Tottenham on Sunday.
Santos led by a stroke from England's Anthony Wall and Scot Peter Whiteford.
Spain's Sergio Garcia, meanwhile, began his season with a 69, but holder Paul Lawrie and Open champion Ernie Els both had to settle for level-par 72s, Els finishing with a bogey six.
Santos made six unsuccessful trips to the qualifying school before coming through the second division Challenge Tour two years ago.
The world number 184 came fourth in Abu Dhabi on Sunday and, after going to the turn in 34, grabbed five front-nine birdies.
Wall and Whiteford are ranked only 231st and 326th respectively, but the Tour's growing strength in depth was further illustrated by them going bogey-free to tuck in just behind Santos.
Former winner Henrik Stenson looked as if he might be the man to catch, but after reaching five under the Swede ran up three bogeys in a row - the last of them are finding the lake at the short eighth, his 17th.
New Zealand's Michael Campbell took another step on the comeback trail with a 68, but South African Retief Goosen, another former US Open champion, could not recover from opening with a double-bogey seven and signed for a 74.
