TAMPA, Fla. -- Alex Killorn credits a little luck in his best ever offensive stretch.
Tampa Bay went ahead 2-1 on Killorn's redirection in the low slot of Anton Stralman's shot at 1:16 of the third.
"Just a play where I was trying to get to the net," Killorn said. "Lucky enough to get a stick on it. Was just hoping it would sneak in."
Killorn has five goals and eight points during a career-best seven-game point streak.
"He's playing the game fast," Tampa Bay coach Jon Cooper said. "When he gets his nose dirty and moving his feet, he was really good."
"You're losing momentum, so we have to get momentum back on our side," Ottawa coach Paul MacLean said. "The only thing you can do is win your next game."
After Morrow scored his first goal in 25 games off a nice backhand pass from behind the net by Cedric Paquette at 8:09, Kucherov's power-play goal made it 4-1 with 6:07 remaining.
"We came out in the third and they put some pressure on," MacLean said. "We didn't handle it."
Legwand, playing in 1,000th NHL game, opened the scoring and snapped a 17-game goal drought when he beat Bishop from the top of the right circle for a power-play goal with 1:47 left in the first.
"Obviously the two points and remembering if you won it would be bigger and nicer, but scoring in it is pretty nice," Legwand said.
Callahan, who had an assist on Killorn's goal, has three goals and six points in the last three games.
Hedman returned to the lineup after missing 18 games with a broken finger.
"It was an unbelievable feeling to get back into action," said Hedman, who played 19:55 and was plus-2. "First game, I was pretty pleased. A great third period got us two points. It's a lot of fun."
Lehner stopped 28 shots.
