Corvo picked up a goal and an assist on seemingly harmless wrist shots from the point to help lead the Senators to a 4-2 victory against the Florida Panthers at BB&T Center.
"My job as a defenseman is to get through the lanes and get the puck to the net so guys can bang in a rebound," Corvo said. "Fortunately, that first one went in."
Colin Greening broke a 2-2 tie with 42.6 seconds left in the second period when Corvo's wrist shot on the power play bounced off his left knee in front of the net, went high in the air and past goalie Tim Thomas.
Greening's goal, his second in 28 games this season, was upheld after video review.
"It's interesting how goals come," Greening said. "They come in all shapes and forms. Tonight was an odd one, but I'll take it.
"I didn't kick it in; it hit off my knee. So, I wasn't worried about the review."
Erik Condra and Bobby Ryan had the other Ottawa goals, and Clarke MacArthur picked up two assists for the Senators, who rallied from an early 2-0 deficit to win for only the third time in their past nine games (3-6-0).
Ottawa goalie Craig Anderson, who had allowed four goals in each of his past four starts, finished with 30 saves. He improved his career record against his former team to 10-1-1. Anderson was a backup for the Panthers from 2006-07 through 2008-09.
"I had to hit the reset button there," Anderson said. "We didn't get the start we wanted. We just got a little [ticked] off there and buckled down. In the second and third, the momentum changed in our favor."
Florida is 1-3-0 on a five-game homestand that wraps up Thursday against the Winnipeg Jets.
"It's frustrating," Campbell said. "It's been very frustrating. I feel like we're close, but we still make those major mistakes that cost us all the time, and they don't seem to be leaving our game. They seem the same amount every night we play. It sums it up."
Thomas, making his 12th consecutive start, finished with 41 saves.
In their first year as Atlantic Division foes, Ottawa has won the first two games against Florida. The Senators won 3-2 on Nov. 9 in Peter Horachek's first game as Panthers coach after he took over for Kevin Dineen.
Ottawa has won 13 of the past 15 meetings between the teams.
Ryan scored the only goal of the third period when he redirected Jared Cowen's centering pass after a turnover at the Florida blue line.
The Panthers, who came in with the NHL's 29th-ranked power play, took advantage of a 5-on-3 opportunity to take a 2-0 lead in the first period.
The Panthers would get another power-play opportunity in the third period, but not before Ottawa had seven of them. The Senators went 1-for-7 with the man advantage; Florida was 2-for-3.
"We had a great start," said right wing Scottie Upshall, who had the first assist on Campbell's goal. "We were playing well. And in the second and third period, we got into penalty trouble. I thought our PK did a great job, but you can't build momentum just killing penalties without creating offense."
Huberdeau opened the scoring at 6:44 of the first when he blasted a rebound of Tomas Fleischmann's one-timer through Anderson's legs. The assist was the first point in 10 games for Fleischmann, Florida's leading scorer in each of the past two seasons.
Campbell scored at 8:22 with one second left in the second Ottawa penalty, a goaltender interference call on Jason Spezza. Campbell took a diagonal pass from Upshall at the top of the left circle, skated in and beat Anderson with a pinpoint wrist shot high to the glove side.
Those were the fastest two goals for the Panthers this season and only the third time they scored twice in the first period.
"We came out, get the 2-0 lead, and it's our job to keep it and not let the momentum switch no matter what happens," Thomas said.
The Senators tied the game before the end of the period, during which they outshot Florida 21-10. After Anderson made stellar pad saves against Upshall and Nick Bjugstad, Ottawa outshot Florida 12-0 over the final 7:40.
"I thought Craig was very competitive tonight, but at the same time was very calm in the net," Senators coach Paul MacLean said. "That was good to see. That gave us momentum after we were down 2-0, and then we were tied up before the end of the period. That certainly helped us a lot."
The Senators ended up outshooting Florida 45-32. The 45 shots represented Ottawa's highest total since the Senators put up 46 shots in a 1-0 victory against the Buffalo Sabres in their season opener.
Corvo cut the Florida lead in half when his wrist shot from the point found its way past three or four players and beat Thomas high to the stick side.
Condra tied the game with 1:15 left in the period after getting knocked to the ice by defenseman Tom Gilbert, getting up and one-timing a pass from Spezza from behind the net past Thomas.
"This was a real important focus game for us to try to get things back on track," Corvo said. "Just play simple and play greasy, get a greasy road win."
Defenseman Marc Methot returned to the Ottawa lineup after missing the Senators' 4-2 loss against the Detroit Red Wings on Sunday because of the flu.
Senators defenseman Chris Phillips played in his 1,100th NHL game.
