With veteran goaltender Grant Fuhr again looking on from the bench, the Calgary Flames won consecutive games for the first time this season.
Brathwaite hadn't played in nearly a month before volunteering to go down to the Saint John Flames of the AHL 10 days ago on a two-game conditioning stint.
"When Grant is in the net, I think the guys are expecting him to do a lot more than he can do," Brathwaite said. "With myself, we're playing a lot better defense and not taking the goalie for granted."
Fuhr has managed a save percentage of .862 among the league's worst since being acquired from the St. Louis Blues in a trade before the season began.
Calgary led 3-0 in the third period when the Islanders rallied, scoring on Webb's goal at 10:04 and then again on the power play at 14:41.
"We had one bad period and it cost us the hockey game," Islanders cach Butch Goring said. "It's more frustrating than anything else."
After firing just three shots at Felix Potvin in a lifeless first period by both teams, Calgary picked up the pace in the second, outshooting the Islanders 16-6 and opening up a 2-0 lead.
"We can't accept starts like that if we want to make the playoffs," Bure said. "It was an embarrassing start but the bottom line is we found a way to win."
Bure's long backhander went off the skate of Islanders defenseman Rich Pilon and trickled through Potvin's legs at 11:56.
At 17:37, Wiemer scored his first of the year when he stepped over the blue-line and ripped a 50-foot slap shot past Potvin to the stick side.
"That second goal really hurt us. I wish I could have that one back," Potvin said. "It's my job to keep those out of the net and keep us in the game longer."
