Steven Stamkos recorded the tying goal with 4.8 seconds left in regulation, and Brandon Hagel scored on a breakaway 1:19 into overtime to give the Tampa Bay Lightning a stunning 5-4 win over the Eastern Conference-leading Boston Bruins on Monday.
Both Stamkos and Hagel added assists as the Lightning won a season-high third consecutive game. Tampa Bay also received goals from Tanner Jeannot, Nicholas Paul and Austin Watson to back 23 saves from Jonas Johansson.
Stamkos' dramatic goal capped a wild third period in which the Bruins scored three times to erase a 2-1 deficit. David Pastrnak and John Beecher scored 1:21 apart to put Boston ahead, though Watson's first of the season forged a 3-3 tie with just over 11 minutes left.
Charlie Coyle briefly sent the Bruins back in front by putting home a feed from James van Riemsdyk with 3:51 left in regulation.
Boston, which got 41 saves from Jeremy Swayman, still managed to extend its point streak to six games (4-0-2). Pastrnak added an assist on Pavel Zacha's goal midway through the first period that tied the game at 1-1.
Stars score five third-period goals to end Rangers' point streak
The Dallas Stars erupted for five third-period goals to end the New York Rangers' 11-game point streak with a 6-3 come-from-behind victory.
Mason Marchment scored the go-ahead goal 7:06 into the third period, and Sam Steel and Roope Hintz each scored short-handed to help the Stars pull away and win for the fifth time in six games.
Hintz added two assists and both Marchment and Joe Pavelski had a goal and an assist to support 30 saves from Scott Wedgewood.
Pavelski started the third-period barrage by registering his eighth of the season just 1:01 into the period, tying the game at 2-2. Six minutes later, Marchment poked the puck past Rangers goaltender Igor Shesterkin on a play that was originally ruled a no-goal before being overturned by a coaches' challenge.
Tyler Seguin later extended Dallas' lead to 4-2 before Steel and Hintz both scored just 1:30 apart with the Rangers having pulled Shesterkin for an extra skater while on a power play.
New York, which came in having won four straight and on a 10-0-1 run, opened the scoring on Vincent Trocheck's power-play goal in the first period. Kaapo Kakko increased the margin in the second before Jamie Benn's goal brought Dallas within 2-1 with 5:37 left in the period.
Shesterkin stopped 30 of 34 shots in the loss.
Predators shock Avalanche with two goals in final minute
Filip Forsberg and Yakov Trenin each scored in the final minute of regulation to give the Nashville Predators an improbable 4-3 win over the Colorado Avalanche.
The Avalanche were well on the way towards a fourth straight victory when carrying a 3-2 lead into the late stages of the third period. However, Forsberg scored his second goal of the night with 37.7 seconds remaining, and Trenin knocked a rebound past Colorado goaltender Alexandar Georgiev with 21.6 seconds left to complete the comeback.
Jeremy Lauzon added a goal and Gustav Nyquist recorded two assists to help Nashville to a second straight win following a four-game losing streak. Juuse Saros finished with 25 saves.
Lauzon scored less than four minutes into the second period to give the Predators a 2-1 lead, but Colorado's Devon Toews tied it later in the frame before the Avalanche went ahead on Valeri Nichushkin's power-play goal with 6:27 left in the second.
Colorado's Andrew Cogliano opened the scoring with a short-handed goal in the first period.
Cale Makar ended with three assists for the Avalanche, who also got two assists from Nathan MacKinnon and 26 saves from Georgiev.
