The Capitals are 30-2-0 this season when scoring first.
"We always get fired up when we get a goal, but there's no relief, like, 'Oh OK, there it is,'" forward Jay Beagle said. "It's not really on our mind. We just want the start, and we obviously are going after the first goal in every game we play. But you score and then you've just got to keep that momentum going."
Staal tied the game at 10:50 of the second period. Staal got a shot off as he worked his way from the right circle to the left and scored on the rebound from the hash marks.
"I thought the young D did a great job and I thought our forwards competed very hard," Carolina coach Bill Peters said.
The NHL's Situation Room initiated a review under the terms of a Coach's Challenge to review whether Capitals forward Evgeny Kuznetsov had possession and control of the puck when Washington entered the attacking zone prior to Ovechkin's goal. It was ruled a legal play.
"We probably still should be out there in some form or fashion maybe overtime or maybe a shootout, I don't know," Peters said. "We'll see what the League says [Wednesday]."
