Rapid Reaction: Rangers 4, Bruins 3 (OT)

What it means: The Rangers erased a 2-0 deficit and rallied to win the game in overtime, narrowly avoiding a series sweep and keeping their playoff hopes alive in Game 4 against the Bruins at Madison Square Garden. Rick Nash connected with Chris Kreider on the rush for the game winner as the Rangers edged the Bruins 4-3 to send the series to Boston for Game 5 on Saturday.

Big goal: The MSG crowd was rocking early in the third when Derek Stepan picked the pocket of Zdeno Chara behind the net to catch an unsuspecting Rask for a quick game-tying wraparound goal at 1:15. The Rangers then whittled a 3-2 Bruins lead at the 10-minute mark with Brian Boyle’s shot from the slot for a power-play goal. It was the Rangers' first power-play goal in 23 attempts.

Seguin snaps drought: Giving the Bruins a 3-2 lead that lasted less than two minutes, Tyler Seguin notched his first goal of the season, scoring on his own rebound at 8:06 of the third.

Rookie wonder: Following up on Nathan Horton’s power-play goal -- the result of a goaltender interference penalty on Rangers forward Kris Newbury -- Boston’s Torey Krug beat Henrik Lundqvist with a one-timer for a 2-0 Bruins lead at 7:41 of the second. The rookie defenseman, who made his NHL playoff debut in Game 1, has three goals in four games for the Bruins. Krug’s goal also came on the power play.

Take a seat: The Rangers cut Boston’s two-goal lead in half with an embarrassing gaffe by Rask. Facing a rush from Carl Hagelin, Rask tumbled backwards, untouched, as Hagelin’s backhanded attempt trickled past the goal line in the second. The Rangers generated momentum from the fluke play, following up Hagelin’s goal with a couple of huge shifts, but didn't tie it up until the final frame.

Surprising scratch: In a bold move before an elimination game, coach John Tortorella scratched struggling center Brad Richards. The 33-year-old veteran, also an alternate captain for the Rangers, was recently relegated to the fourth line with which he received just 8:10 of ice time in Game 3, only 5:58 of which was even strength. Rugged winger Arron Asham was also scratched, with depth forwards Newbury and Micheal Haley replacing the two veterans in the lineup.

Depleted D: The Rangers were without top-four defenseman Anton Stralman, who suffered an injury in Game 3 after taking a hard hit from Boston’s Milan Lucic late in the second period. Veteran Roman Hamrlik took Stralman’s place, making his first appearance in almost two months.

What's next: An all-or-nothing Saturday in Boston, faceoff at 5:30 p.m. ET.
