"I thought we had a better physical effort, we actually skated and tried to create but the polish around our play and the fundamentals that go into a game night in and night out were very rusty," said Oilers Head Coach Todd McLellan.
Adam Larsson scored the only Oilers goal of the game, Cam Talbot made 19 saves on 23 shots but was later replaced by Laurent Brossoit, who made six saves on eight shots.
Special teams disadvantaged Edmonton, as the Senators went 3-for-5 on the man-advantage while the Oilers failed to score on their three power plays.
"To me, we don't have that threat of a shot right now," said McLellan of the special teams. "Whether it was Test (Letestu) or Klef (Klefbom) last year, we seem to want to play from those shooting spots, back over to Connor, and then make plays off that. We're too predictable."
Desperate for a win after dropping two straight then holding three consecutive practice days, the Oilers did not get out to the start they intended against the Ottawa Senators on Saturday.
The Sens jumped out to a 2-0 lead midway through the opening frame, getting goals from Hoffman and Derick Brassard.
On Hoffman's marker, Tom Pyatt fed a pass from the corner of the Oilers zone and the winger got enough of his blade on the puck to put it past Talbot at 6:09.
Brassard's tally came while Zack Kassian was in the box for hooking. Rookie defenceman Thomas Chabot worked the puck from the point to Mark Stone on the left half wall. Stone threaded the puck across the ice to Brassard, who teed up a shot that beat Talbot blocker side at 9:31.
"I'm concerned because I think we need to play the game faster," said McLellan. "We're torn between not scoring and giving up too many."
The Oilers were held to one shot halfway through the period but turned up their play in the final five minutes of the frame. Deflection attempts from Yamamoto and Patrick Maroon almost got the Oilers on the board late in the frame but Mike Condon stopped both attempts. Yamamoto finished the period with four shots on goal.
"You look for bright spots on a tough night and he would have been one of them," McLellan said of Yamamoto. "He played very fast, he played quick, he had his nose over the puck in and around the blue paint a number of times, he had an impact on the game offensively and didn't hurt us defensively."
Milan Lucic, who fought Mark Borowiecki 48 seconds into the game, followed up the Oilers top line shift by springing Kassian on a breakaway. The Oilers forward approached Condon all alone but a slash from Borowiecki caused the feisty winger to crash into the post. Borowiecki was called for slashing, sending Edmonton to the power play for the first time of the night.
Edmonton increased their tempo in the second period but the Senators increased their lead.
Hoffman scored his second goal of the game at 3:36 of the middle period. Turris found the forward in the slot and the sniper wasted no time in releasing a wrist shot above Talbot's glove to make it 3-0 Senators.
The Oilers - desperate for offence - threw everything they could at Condon, registering 19 shots on goal in the period. The best Oilers chances came from a Yamamoto one-timer and a McDavid rush that saw the Oilers Captain go inside-outside on Stone then just miss Patrick Maroon with a backhand pass on the doorstep.
"Adjusting to the way they check in the neutral zone took a little while," said Mark Letestu. "Once we made the adjustment, we carried the play for the last little bit of the first and most of the second."
The Sens poured it on in the third.
The visiting team scored their fourth goal of the game just 1:04 into the final period. Turris' wrist shot from the right side was stopped by Talbot but the rebound bounced off of Larsson's leg and past the Oilers keeper. Brossoit came in for relief of Talbot after the goal.
"It's not good enough," said Talbot of the game. "We got down early, a couple bad decisions on my part and it put us in a hole... We got in a hole and couldn't dig ourselves out."
Lucic was called for interference soon after and the Senators capitalized. Chris Wideman's slap shot from the point beat Brossoit to give the Sens a 5-0 lead at 3:43.
Edmonton continued playing undisciplined, as Eric Gryba took two penalties simultaneously in the third period. He was called behind the Oilers net for cross-checking and roughing, giving the Senators a four-minute power play.
The Oilers were able to kill the two penalties but Turris scored his second of the period at even strength after walking through three Edmonton skaters then lifting a wrist shot over Brossoit's blocker, giving the Senators a punishing 6-0 lead.
Larsson broke Condon's shutout bid at 11:03 with a slap shot from the blueline but the damage had already been done.
The Oilers host the Carolina Hurricanes Tuesday at Rogers Place. Puck drop is at 7:00 PM MDT.
