In a matinee matchup Saturday, the Ducks had no answers for the Ottawa Senators.
Linus Ullmark made 23 saves and the Ducks were shut out for the second time in four games in a 2-0 loss at the Canadian Tire Centre in Ottawa.
The Ducks couldn’t find the back of the net on any of their 23 shots, including on four power-play opportunities.
Ville Husso stopped 27 shots for the Ducks (36-27-3), who have now lost three of their last four games and are in peril of falling out of the Pacific Division lead.
For Ullmark, it was his second shutout of the season and 14th of his career. Ottawa has now won four of its last five games.
The Ducks were playing the first of five games without captain Radko Gudas. The defenseman was suspended five games by the NHL for a knee-to-knee hit on Toronto’s Auston Matthews that knocked the Maple Leafs start out for the season during a 6-4 Ducks loss Thursday.
Michael Amadio and Thomas Chabot scored for Ottawa (33-23-9), with Shane Pinto notching two assists.
Pinto fed Amadio on a 2-on-1 and the former King beat Husso short-side 3:54 into the second period.
Less than seven minutes later, Pinto intercepted a pass and found Chabot in the high slot for a short-handed goal. The Ducks challenged for goaltender interference but were unsuccessful, even though it appeared Tim Stutzle’s skate made contact with Husso in the crease.
Husso made two key saves in the first period, stopping Amadio on a shorthanded 2-on-1 and denying Stutzle with a glove save on a Senators power play.
Stutzle almost made it 3-0 with his goal in the third period, but Ottawa was called for goaltender interference.
The Ducks wrap up their four-game Canadian sojourn Sunday at Montreal before coming home and taking on Philadelphia on Wednesday.
