OTTAWA -- Chris Phillips waited a long time to reveal his offensive skills.
Phillips, who entered with one goal in 18 games, scored goals 2:03 apart in the third to put Ottawa up 5-1 and chase Pittsburgh goalie Marc-Andre Fleury.
"I'm not expected to, for sure," Phillips said. "It feels good to do it and it felt like one of those high energy games, for us anyways, and it's nice."
"Philly had to wait until his 800th to get two in a row but that was pretty sweet," Carkner said. "He played really well tonight for us, a solid game and just that he got those two goals was huge for us. We're very proud of him."
Fleury, who made 19 saves, left 7:12 into the third after allowing five goals. Brent Johnson stopped six of seven shots the rest of the way.
Talbot, who had surgery on his left shoulder in July, played for the first time since scoring both goals in Pittsburgh's 2-1 win over Detroit last spring in the seventh game of the Stanley Cup final.
"It definitely feels good to be back," said Talbot, who was called for tripping on his first shift and played a total of 13:17. "Obviously you want to come back in a winning situation but personally I think I was lucky enough to have a couple of good shifts and I had ice time so it's good to be back out there."
Gonchar, who missed 12 games after he broke his left wrist on Oct. 20, played 25:30, the most ice time of any player on either team.
"I think good additions back in our lineup," coach Dan Bylsma said. "It was our first game for Max in a long, long time and he brought his energy and he was effective, he was effective in the offensive zone and I liked that. Sergei, we asked him to play a lot of minutes tonight. It's tough for him to get back in there but definitely our power play's a bit more dangerous with him out there."
Carkner got his second goal of the season 12:16 in on a slap shot past Fleury to tie it at 1 after Staal deflected Pascal Dupuis' pass beyond Leclaire to give Pittsburgh an early lead.
Michalek reached his milestone to give Ottawa a 2-1 lead on a power play 2:31 into the second. He deflected Daniel Alfredsson's slap shot past Fleury for his ninth goal of the season.
Kelly, who was sent off for tripping with 49 seconds left in the second, scored his first goal of the season on a breakaway 1:29 into the third after coming out of the penalty box to put Ottawa up 3-1.
"Right after the power play's over within a 30-second span we're down 3-1 and they had the momentum at that point," Bylsma said.
Phillips drove a slap shot past Fleury at 5:09 and scored again at 7:12 for his first multigoal game since Nov. 22, 2001.
Cheechoo beat Johnson with an unassisted effort for his second goal at 13:06.
Malkin scored his fifth on a power play at 17:19.
