BUFFALO, N.Y. -- With the game on the line, the Buffalo penalty killers came up big.
Ahead by a goal but down a man and without one of their best penalty killers, the Sabres erased a major boarding penalty on Clarke MacArthur with 6:15 left. MacArthur was given the penalty, along with a game misconduct, after ramming Oilers forward Liam Reddox headfirst into the boards.
The Sabres allowed just two shots and had two blocks during a kill that was missing Mike Grier, who had left earlier in the period because of a groin injury. The defensive-minded Grier is day-to-day.
"The guys did a fantastic job of trying to be real aggressive on the puck carriers," Buffalo captain Craig Rivet said. "We were able to get through it."
Reddox, meanwhile, will need X-rays on a swollen wrist after a violent collision with the boards. He also sustained a cut on his face.
"Watching it on tape, [MacArthur] knew exactly what he was doing," Oilers coach Pat Quinn said. "I don't have anything to say on it. His head got smacked, and he took a pretty nasty hit."
Tim Connolly also added a pair of assists in Buffalo's fourth straight win over Edmonton.
After an 8-1-1 start, the Sabres found themselves slumping after losing three of four. But they rebounded and killed off six of Edmonton's seven power-play opportunities.
"We were scrambling around," Edmonton forward Patrick O'Sullivan said. "That's the way it's been lately -- not quite able to get the goal when we needed it."
O'Sullivan scored the lone Edmonton goal, and Nikolai Khabibulin made 23 saves for the Oilers (8-9-2), who have lost five of six.
O'Sullivan also hit two posts in the game, the first coming midway through the second period, and the second with less than 2 minutes to go during the long power play.
"The one positive thing is we're playing a lot harder," he said. "We didn't get the result tonight, but we certainly applied more pressure and limited the other team's shots."
Stafford opened the scoring with 4:29 left in the first period when he lifted a backhander from in tight over Khabibulin's left shoulder for his team-leading fifth goal.
Buffalo made it 2-0 when Montador fired a slap shot from the right circle for his first goal of the season, scored at 7:34 of the second.
While the Oilers were on a two-man advantage, O'Sullivan cut the deficit in half with his third goal. He one-timed a feed from Ales Hemsky with 2:11 left in the middle period.
Hecht capped the scoring with an empty-net goal with 19 seconds to go.
"We took some penalties we didn't want to take, but we'll move forward," Miller said. "Our desperation was really high and I thought we did a great job of holding on for the win."
