ANAHEIM — The Ducks held their own against one of the NHL’s top teams, the Vegas Golden Knights, but lacked finishing ability once more in a 3-2 loss at Honda Center on Wednesday night.

They fell to 0-2 against Vegas, which they beat in three of four meetings last year, and have lost five of their past six games overall.

Brock McGinn and Frank Vatrano scored a goal apiece for the Ducks in support of Lukáš Dostál, who made 37 of 40 saves. Brett Leason assisted on both goals. Cam Fowler (upper body) and Robby Fabbri (lower body) were both placed on injured reserve, while Mason McTavish (upper body) also missed the match but remained day-to-day.

Centers Nicolas Roy and Tomáš Hertl each snagged a goal for Vegas, as did winger Pavel Dorofeyev. Former Ducks defenseman Shea Theodore contributed two assists. Adin Hill came up with 22 stops.

As the game wore on, Killorn was unable to put a point-blank shot into an open net on goal, Leason was robbed on a sterling chance and a failed power play pushed the Ducks to zero-for-three on the evening. Killorn assisted on Vatrano’s one-timer with 12.5 seconds to play after Leason’s silky move at the blue line drew a crowd of defenders, allowing him to slip the puck to Vatrano for a goal that saved the Ducks from their sixth one-goal output in 15 games. Vatrano, who had 37 goals last year, has just two thus far.

Vegas extended its edge to 3-1 at the 4:29 mark of the third period. Dorofeyev picked off a casual pass from below the Ducks’ goal line by Isac Lundeström, placing one shot on net and then scoring off a second for an unassisted goal that gave him 10 points in his past 10 games.

Though a pair of penalties were not called — what likely should have been a double-minor for the high-sticking that sent Jansen Harkins back to the dressing room and a slash that prevented a Ryan Strome putback late in the second period — the Ducks began the final frame on an unsuccessful power play.

Vegas out-shot the Ducks handily in the second stanza and had the period’s only goal as well as a second-intermission lead to show for it.

Hertl and his unit needed just 15 seconds of power-play time as they won a faceoff to set up a Dorofeyev one-timer from the right circle. After Dostál beat back the initial shot and Hertl’s follow-up, Hertl moved the puck from low to high, where it moved across the top of the umbrella to set up a Jack Eichel heave on net. Hertl popped in the rebound for a go-ahead goal at the 6:43 mark. Eichel entered the match with eight points in his past three games.

The Ducks played a sound first period, killing the game’s first penalty and generating high-quality chances, including their ice-breaking goal with 2:21 left.
