Senators top Bruins on Brady Tkachuk's OT winner

Brady Tkachuk scored 21 seconds into overtime, finishing with a goal and an assist, as the visiting Ottawa Senators beat the Boston Bruins 3-2 on Saturday.

Boston went the entire third period without a shot on goal, but its goaltender, Jeremy Swayman, made 12 stops in the frame -- including one on a Thomas Chabot drive with two minutes remaining -- to send the game to overtime.

In the extra session, Tkachuk slotted home a wrister from the right circle after Ottawa goaltender Linus Ullmark stopped a one-time drive by Elias Lindholm at the other end of the ice.

Josh Norris and Michael Amadio also scored, while Ullmark made 14 saves for the Senators, who broke a two-game losing streak.

Pavel Zacha and Brad Marchand scored Boston's goals in the second period, turning a 1-0 deficit into a 2-1 lead within a 15-second span.

Matching up against his former Bruins goaltending partner, Swayman made 31 saves in the losing effort. It was Boston's second straight overtime game.

Ottawa had a 34-16 advantage in shots on goal.

Ullmark made one of his best saves in the opening six minutes, moving to his right to deny Trent Frederic's drive from the right circle to help his team take a 1-0 lead into the first intermission.

Norris put Ottawa on the scoreboard with just 7.8 seconds remaining in the first, taking Tkachuk's feed to the right circle for an open one-time snipe on the power play.

The Bruins' rapid-fire goals followed a penalty kill for too many men on the ice only 52 seconds into the middle frame. Zacha started the spurt at the 4:51 mark, firing a turnaround shot from the slot past Ullmark after a Nikita Zadorov keep-in and a David Pastrnak pass.

After Ullmark stopped a Hampus Linhdholm try, Marchand cleaned up a loose puck at the right crease to give Boston a 2-1 lead at 5:06.

Leading into another successful Boston penalty kill, Swayman made an important stop off Tkachuk's backhand on the breakaway to preserve his team's 3-1 lead with 8:35 left in the second.

The teams went into the second break in a 2-all tie , though, as Amadio beat Swayman with a clean snipe from the top of the right circle with 2:44 to go.
