Ducks’ goalie Viktor Fasth stymies Avalanche, 3-0

The Ducks’ winning streak climbed to four games Wednesday as rookie goaltender Viktor Fasth continued his unexpected dominance in a 3-0 victory at Colorado.

Fasth, who began the abbreviated season as a likely seldom-used backup to Jonas Hiller, is 4-0 as a starter after keeping the Avalanche scoreless on 31 shots.

“The most important thing is a win and a good start to the trip,” Fasth said. “It’s special to get a shutout, a nice little bonus. I’m just trying to do my best.”

Opening a six-game trip that will feature stops at St. Louis, Chicago and Detroit over 11 days, the Ducks charged to a 2-0 first-period lead en route to becoming 3-0-1 on the road.

Defenseman Sheldon Souray, after scoring the deciding goal Monday to hand San Jose its first loss, fired a shot from the blue line past goaltender Semyon Varlamov 6 minutes 20 seconds into the game.

The assist by Ryan Getzlaf extended the center’s scoring streak to five games.

“We are finding good chemistry and settling into our roles,” Souray said.

Saku Koivu scored a goal in his second game in a row, getting a tap-in on a five-on-three advantage with 4:18 left in the first period.

“It’s a good start,” Koivu said. “I’m still surprised, but I’m enjoying it.”

Fasth, a 30-year-old rookie from Sweden, was awarded with his first back-to-back start after limiting high-powered San Jose to one goal with 25 saves in Monday’s triumph.

“He’s playing really, really well,” Coach Bruce Boudreau said. “Our goalie stole a victory for us. He played great.”

In lifting the Ducks atop the Pacific Division, Fasth became the first NHL goaltender over age 30 to win his first four games. He is the first since San Jose’s Nolan Schaefer in 2005 to debut with four straight victories.

Asked about Fasth’s role on the depth chart, Boudreau said, “It doesn’t hurt, and if he keeps playing like that. … Hiller will be playing soon, and doing the same thing, I hope.”

Defenseman Francois Beauchemin, playing in his 500th game, extended the lead to 3-0 nearly midway through the second period.

During the game, the Ducks announced they acquired fifth-year defenseman Ben Lovejoy from the Pittsburgh Penguins in exchange for a fifth-round pick in the 2014 NHL draft.

The 6-foot-2, 215-pound Lovejoy, 28, is scoreless this season. His best season was 2010-11, when he had 17 points (three goals).

Earlier Wednesday, the Ducks moved Jordan Hendry to Norfolk, their minor league affiliate.
