ATP Cup: Medvedev takes the offensive to check Fognini fading

PERTH (Australia): world number five Daniil Medvedev backed his attack instincts and came from behind to beat Fabio Fognini , while Russia was sweeping Italy on the opening day of the inauguration ATP Cup on Friday.

The US Open finalist overcame a slow start to prevail 1-6, 6-1, 6-3 in one hour and 47 minutes after world number 17 Karen Khachanov had crossed to a 7-5 victory, 6-3 over Stefano Travaglia .

I am not happy with some moments of my performance, but I am happy to get the victory for my country, Medvedev said. Fabio destroyed me in the first set. I knew I had to play much more aggressively in the second set and it worked very well.

Medvedev and Khachanov combined to beat Paolo Lorenzi and Simone Bolelli 6-4, 6-3 in the doubles.

Russia arrived early in Group D along with Norway's surprise packages, which surprised the United States with a 2-1 victory.

Medvedev received a code violation in the middle of the first set after hitting a ball in the stands. When the world number 12 Fognini crossed the set with exquisite time and precise precision, the overwhelmed Russian seemed to boil again.

Instead, an aggressive Medvedev found his rhythm and hit the lines to move his tiny opponent across the court.

Fognini, 32, seemed tired of having arrived in Perth on Thursday after the recent birth of his second son.

Khachanov also started slowly, but proved to be too strong for Travaglia, who represented his country for the first time.

Travaglia, in 84th place, surprisingly won an early dominance against a messy Khachanov by mistake to lead 5-2, but failed to close twice in his service. The 23-year-old made him pay and got rid of five consecutive games to claim the first set with a setback winner.

Khachanov only needed a break in the second set to put Russia in the lead.

Previously, the young emerging Casper Ruud won the biggest victory of his career after beating John Isner to lead Norway's victory over the United States.

The 21-year-old tied the tie with a 6-7 (3/7), 7-6 (12/10), 7-5 beat the world number 19 in two hours and 43 minutes.

He saved two match points in the second set and surpassed 33 aces of Isner, after Taylor Fritz hit Viktor Durasovic 6-2, 6-2 in the opening game.

Ruud then backed that victory in the decisive doubles alongside Durasovic, beating Rajeev Ram and Austin Krajicek 4-6, 6-3, 10-5 and unleashed jubilant scenes from the Norwegian contingent, which was the last team to qualify for 24- National event that is also played in Brisbane and Sydney.

I didn't have much time to recover from my singles, Ruud said. It was a little low (in energy), but I set foot and we played very well. The players are very proud to beat the United States.

The world number 54 has risen in the ranking over the past year since training with Rafael Nadal at the world's number one academy in Mallorca.

The new tournament replaced the Hopman Cup, a popular annual mixed team meeting in Perth for three decades.
