TOP seed David Ferrer was forced to come from a set down against qualifier Dustin Brown before moving into the second round of the Qatar Open.
Brown made a nonsense of the 162-place gap in the rankings to take the first set but the Spaniard recovered to prevail 5-7 6-3 6-2.
Brown, of Germany, fired down eight aces in the first set and took advantage of his three break-point opportunities to take the opener and pose the possibility of a huge shock.
Ferrer was much improved in the second and final sets and gave his opponent little chance.
Although Brown sent down a further six aces, he could not repeat his exploits of the first set with the match over in two hours and 33 minutes.
Mikhail Youzhny beat Benjamin Becker 4-6 7-6 (7/3) 6-1.

Second seed Richard Gasquet went through in an hour and a quarter with a 6-3 6-4 victory over qualifier Jan Hernych.
