ROGER Federer has maintained his career-long winning streak over David Ferrer to advance to the quarter-finals of the ATP Montreal Masters after a three-set battle with the veteran Spaniard.
Federer, 36, had never lost in 16 previous meetings with the 35-year-old Ferrer, who he first defeated 14 years ago at the Vienna Indoor tournament.
But while Ferrer managed to take the opening set - ending Federer's 32-set streak - the Swiss ace raised his game to win 4-6 6-4 6-2.
A strangely error-prone Federer was unable to generate his usual fluency early on, and quickly found himself giving away early breaks to trail 4-1 in the first set.
Nowhere was Federer's wayward performance better illustrated than in the seventh game, when he squandered three break points at 0-40 to allow Ferrer to hold to take a 5-2 lead.
Federer held for 5-3 and looked to have clawed his way back into the set with a break of Ferrer's serve in the next game to make it 5-4.
But Federer was struggling again as he served to level the set, finding himself set point down. He saved the first with an ace but Ferrer made no mistake with his second set point, converting to take the opener 6-4.
Federer responded quickly in the second set, going a break up to lead 3-2 before holding for a 4-2 lead.
With Federer slowly improving his first serve, Ferrer was unable to carve out the break opportunities he had found in the first set.

Some vintage play at the net helped put Federer 4-2 up with Ferrer seemingly unable to summon a response.
The decisive break came in the seventh game, with Ferrer netting a forehand return to leave Federer 5-2 up and serving for the match.
Federer promptly went in for the kill, attacking the net and opening up the court to clinch victory with a deft volley.
Federer will now play another Spaniard, Roberto Bautista Agut, in the quarter-finals. Bautista Agut defeated France's Gael Monfils in a gruelling slugfest, winning 4-6, 7-6 (7-5), 7-6 (7-2).
