Jay McClement, on the 30th attempt, scored the only shootout goal after he had tied the game with 4:37 left in the third period.
"At one point I think both refs were just going to call it a draw and kind of pick up the puck and go home and be old-school NHL there for a second and call it a tie," Sabres forward Steve Ott said, according to The Canadian Press. "But both performances by both goalies in the shootout was pretty spectacular to watch. I've never seen that before."
Jhonas Enroth made 32 saves for the Sabres before stopping the first 14 shootout attempts he faced. Paul Ranger, in the 10th round, tried a kick-shot to beat Enroth, which upset the goaltender at the time.
"My first reaction was that he tried to embarrass me there a little bit, but when I look at it now, it's good [the] guy's trying to be creative, I guess," Enroth said.
Reimer's final save in game action was on a Jamie McBain breakaway right before the overtime buzzer. The goalie was 0-5 in shootouts last season.
"It's good to get out there and for me to stop some pucks and for guys to get some reps, but it's exhibition and it's a little looser," Reimer said. "I think it's a little different when it's during a game and two points are on the line."
The longest regular-season shootout is 15 rounds between the New York Rangers and Washington Capitals, won by a goal, the seventh of that tiebreaker, from New York's Marek Malik on Nov. 26, 2005.
