Ruud matched the Group D draw in Perth in just 66 minutes and then backed with Viktor Durasovic in the decisive doubles only to be thwarted by Fognini and Simone Bolelli, who prevailed 6-3, 7-6 (7/3).

Italy joined Norway's surprise packages with a 1-1 record so far after being swept by Russia in their first game on Friday.

Ruud, whose father Christian is the captain of Norway, has led his team's amazing career, starting the season spectacularly after not only annoying Fognini but American John Isner in his first victories over the top 20 players.

I am very happy to beat my top ranked player, he said about Fognini.

Coming here and beating two of the top 20 players at the beginning of the year is great for my confidence.

The world number 54 was in an imperative form with a series of precise shots in the baseline that shook a frustrated Fognini, who mishandled several right-handed shots.

Ruud broke down twice to extract the first blood and his precise service gave him little chance of venturing into the Italian. He broke into the sixth game of the second set to grab a domain on the way to his second consecutive surprise.

In the previous individual game, Stefano Travaglia achieved his first victory of the season after comfortably beating Durasovic 6-1, 6-1 in 56 minutes.

The world number 84 took advantage of a malfunction of Durasovic, which had 16 unforced errors in a first set of terror. The unilateral competition continued with Travaglia giving Italy its first taste of victory.

The 28-year-old represents Italy for the first time after replacing world number eight Matteo Berrettini, who retired from the tournament due to an abdominal injury.

It is very important for me to play for Italy, Travaglia said. I tried to play every point at my best and I think I did.

Durasovic, ranked 332, has not won a set in two games after winning just four games against American Taylor Fritz in his first game.

Russia led by Daniil Medvedev faces the United States in the subsequent draw of Group D.
