Crosby scored 43 seconds into overtime, snapping a career-high nine-game scoreless streak, and lifting the Penguins to a 4-3 victory over the Buffalo Sabres on Monday night.
Pittsburgh, which improved to 4-5-1 in December, also rebounded from one of its poorest efforts of the year on Saturday in 7-3 loss to Toronto.
"We bounced back from last game and played a good hockey game," Crosby said. "We were working hard, and I thought we deserved to win. Hopefully we can build off of this."
Crosby stopped his drought when he tipped in Evgeni Malkin's shot past goalie Ryan Miller. The play survived a 2-minute video review that confirmed Crosby's stick was under the crossbar when he touched it.
"It was pretty close," said Crosby, who scored for the first time since netting a hat trick against New Jersey last month. "But I don't think it was [a high-stick]. My stick was angled down. If I would have hit it a little higher up, I think we would have been flirting with danger a little bit more."
"I didn't get a great look, but from my gut feel I thought it was a little high," he said. "Let's just hope they make the right call in Toronto."
"We haven't been playing that well, so that's a great road win against a good team," Goligoski said. "It's good for the locker room right now."
Pascal Dupuis also scored, and Malkin had three assists for Pittsburgh (18-11-4), which won for the second time in three games.
"We are managing the puck really well and we found a way to comeback," Penguins coach Michel Therrien said. "To be able to win that game in overtime, it's a big boost of confidence."
Miller finished with 18 saves.
Down by a goal after two periods, Pittsburgh tied it 3-3 on the power play on Goligoski's second of the game, a wrist shot from the middle of the blue line that got past a screened Miller with under 9 minutes left in regulation.
Paille opened the scoring with his fourth of the year just a minute into the game. From the top of the right circle, Paille sent a shot toward the Pittsburgh net that ricocheted off defenseman Philippe Boucher's skate and into the net.
Kotalik upped the Sabres' lead to 2-0 with his eighth 5:23 into the second period. After taking a feed from Paille, Kotalik went in alone on Fleury from the blue line and wristed a shot from the slot over the goalie's glove hand.
Dupuis cut the deficit in half with his seventh 55 seconds later, sending a wrist shot from the slot that squirted between Miller's right arm and body.
Goligoski tied it at 2 with 7:37 left in the second, netting his fifth of the year when his wrist shot from the right point eluded Miller, but MacArthur's power-play goal with 4:02 remaining gave Buffalo the lead again.
"We played hard, so it was a tough break," Sabres coach Lindy Ruff said. "I thought our guys did a great job against a very skilled team."
