The top-seeded pairing of Nadia Petrova and Dmitry Tursunov was far too good for the Spanish duo of Annabel Medina Garrigues and Tommy Robredo.

The Russians, who were pre-tournament favourites but had to recover from dropping their first Group A tie to Australia, wasted little time claiming the title with straight set wins in both singles matches.

Petrova outclassed Medina Garrigues while the big-hitting Tursunov produced clearly his best singles form of the week to overpower a plucky Robredo, who was chasing his second Hopman Cup title after teaming with Arantxa Sanchez Vicario in 2002.

The Russians claimed a pair of diamond-encrusted tennis balls and a cheque for 250,000 Australian dollars (195,000 dollars) and Petrova could barely believe her good fortune.

"I cannot believe we are holding these balls," she said.

"They way we started here, we were not thinking it would end us this way, but it ended up great.

"Dmitry really showed heart today."

Tursunov, who helped Russia win its second Davis Cup recently, said it was great to continue his country's impressive form in international team tennis.

"It is really nice for our country," he said.

"After Fed Cup and Davis Cup, I don't know if there are any more to win."

With victory within reach, Tursunov recovered from a break down in the second set to clinch the title with a 6-4, 7-5 win in 88 minutes.

Robredo was able to save one match point in the second set, but Tursunov produced a clinical backhand down the line to earn another as an anxious Petrova watched on.

Tursunov then appeared to claim victory with a crunching crosscourt forehand that a stretching Robredo could only float into the net, but the Russian had to wait for the Hawkeye electronic system to review the call.

The review showed the ball had just caught the outside of the line and was good, confirming Tursunov's win.

Tursunov, ranked 15 places below Robredo at 22nd in the world, had been very disappointing in singles losses to Mark Philippoussis and Mardy Fish earlier in the tournament.

However, he was at his best against Robredo, hitting 29 winners to Robredo's 13.

Robredo looked set to level the match when up a break in the second set, but Tursunov then lifted his game again.

The women's singles was a one-sided affair, with Petrova having few problems giving her team a perfect start to the tie with a straight sets win over Medina Garrigues in 64 minutes.

Petrova, ranked sixth in the world, breezed through the first set without dropping a game and her only hiccup came when she handed back a break to the Spaniard in the second set, but she recovered to win 6-0, 6-4.

It was her second easy win in as many meetings with the 27th-ranked Medina Garrigues.

Petrova's serve gave her six aces, while Medina Garrigues managed just one.

The Spaniard spent most of the match just scrambling to stay in points and throwing up defensive lobs and as a result hit just two winners, while Petrova reeled off 19, of which 12 were produced by her forehand.

Petrova said Medina Garrigues had been a tricky opponent and that her own form had been very pleasing.

"She stands very close to the base line and she plays with very heavy spin," she said.

"It is very difficult to do something.

"What I basically had to do is push her behind the baseline as far as possible and try and find a short ball to finish it off, it was working great.

"Unfortunately when I had to serve at 4-2 my nerves kicked in and it didn't work out.

"At the beginning of the season you have to go through it again and learn how to manage your nerves and I'm very happy that I could manage it."
