Swiss master Roger Federer beat Germany's Florian Mayer 6-4, 6-3 to win the Stockholm Open tennis tournament on Sunday and equal Pete Sampras's haul of 64 ATP titles.

“It's fantastic to come here, face the pressure and be able to come through at the end,” the World No. 2 told Swedish TV.

“It was a really difficult final and you can see I'm still breathing hard. I thought Mayer played a terrific final so I'm very happy.”

Mayer, without a title to his name, had a mountain to climb but came out strongly, attacking at every opportunity and displaying a fine touch around the net. He broke serve in the first set, only for Federer to break back immediately.

The Swiss then held his own serve to love before breaking again to take the set.

Mayer wrong-footed Federer with some classy shots but a service break in the sixth game of the second set put the 16-time Grand Slam winner in the driving seat.

“It's been a tough week. I came from Shanghai where I played five matches, then the jet lag and the whole thing, so to back it up with another win is great,” said Federer after picking up the trophy from Crown Princess Victoria.

Maiden title

In Moscow, unseeded Serb Viktor Troicki battled back from a set down to win his maiden ATP title, beating fourth seed Marcos Baghdatis of Cyprus 3-6, 6-4, 6-3 in one hour 43 minutes.

“Marcos (Baghdatis) was playing very good in the first set,” Troicki said. “But then I started playing better and better and at the end I won my first title. It feels unbelievable to win!”

“I like to play in Moscow very much. Next year I will come back to defend my title here.”

The finalists traded breaks early on, but the 25-year-old Cypriot edged ahead to take the opening set in 30 minutes.

It was tight again in the second set up until the 10th game, when Troicki, 43rd in the ATP rankings, broke to level at one set all after one hour eight minutes on court.

Troicki broke halfway into the deciding set again for a comfortable 4-1 lead, which he held on to win the match converting his first match point with a forehand volley.

Earlier, second seed Victoria Azarenka of Belarus won the WTA section of the tournament defeating Russia's Maria Kirilenko 6-3, 6-4 in the final.

The 21-year-old won 6-3, 6-4 in one hour 55 minutes to level her head-to-head record with Kirilenko at 2-2.

Currently 10th in the WTA rankings, Azarenka started the match with a break of serve but Kirilenko, who was seeded sixth, broke back immediately to level at one game all.

Azarenka looked more focused and powerful and she grabbed two further breaks to gain a one-set advantage in 47 minutes.

Kirilenko picked up steam in the second set breaking serve twice in a row to jump out into a commanding 4-0 lead before Azarenka moved up a gear and won six consecutive games to clinch her fifth career title.

“It was really tough to win the second set as Maria started pretty good dominating the play completely,” Azarenka said. “I'm really happy to win here at my third attempt though I still do not understand completely what I've done,” she added.
