Mantha gave Washington the lead back at 2-1 at 14:03, driving in and beating Bobrovsky with a high tip-in of a sharp pass from Michael Sgarbossa.
“I thought we battled pretty hard,” Mantha said. “We need to come together, obviously, and that’s the only way we’re going to come out this. There is enough talent, the right attitude and compete level in this room to look at what’s ahead and know we can do it.’’
Sam Reinhart scored his NHL-leading 21st power-play goal by deflecting a point shot from Tkachuk at 17:32 to tie it 2-2.
Reinhart’s 13-game point streak ended Tuesday, but he has 20 goals (including 13 on the power play) in his past 19 games.
“I just saw him by himself, and when he’s by himself, you try to find that stick,” Tkachuk said.
NOTES: Bobrovsky stopped Washington forward Beck Malenstyn on a penalty shot, making a blocker save at 8:31 of the first period after Malenstyn was hooked by Oliver Ekman-Larsson. … Sgarbossa got his first point of the season after making his debut Tuesday against the Montreal Canadiens. … Ovechkin has 89 points (44 goals, 45 assists) in 71 games against Florida. He ranks first in career goals, assists and points against the Panthers. … Tkachuk had his eighth multipoint game since Dec. 29. During that 17-game span, he has 30 points (12 goals, 18 assists).
