It's official. The Bruins will face the Toronto Maple Leafs in the first round of the Stanley Cup playoffs, thanks to a 4-2 loss to the Ottawa Senators on Sunday night at the TD Garden to conclude the regular season.

Had the Bruins won in regulation, they would have faced the New York Islanders. Had they won in either overtime or a shootout, they would have faced the Senators.

But Ottawa broke a 2-2 stalemate with 3:34 left in regulation on a Jean-Gabriel Pageau goal from the left post after Marc Methot's shot from the left point hit Bruins defenseman Adam McQuaid. Tuukka Rask was caught going to his left, and the puck stayed to his right, where Pageau put it home into the open net.

Kyle Turris made it a 4-2 lead with an empty-netter with 36.5 seconds left in the game.

Erik Condra originally put Ottawa up 1-0 with 3:01 left in the first period, after he knocked home a rebound on a Pageau shot from the high slot.

Condra avoided a hit from Johnny Boychuk at the left half-wall, but then got up to take a loose puck into the left circle, where he slid a pas back to Pageau at the high slot. Condra kept skating hard to the net and swooped in on the rebound.

Jared Cowen gave the Senators a 2-0 lead midway through the second period, when his shot from the middle-point beat Rask to the low-right side of the net.

The Bruins cut that lead to 2-1 with 3.4 seconds left in the second after Rich Peverley put a quick wrister low-left from the right circle, while on a 5-on-4 power play. Defenseman Wade Redden did the dirty work, taking the puck down the right boards and taking a big hit at the half-wall while sending the puck out to a streaking Peverley in the right circle.
