OTTAWA (AP) -- Peter Regin got his third power-play point of the game with an assist on Chris Phillips' goal midway through the third and the Senators extended their winning streak to five with a 3-2 victory over the St. Louis Blues on Thursday night.
Regin, who opened the scoring in the first, got his second assist of the game as Phillips put a wrist shot from the slot past Chris Mason 10:29 into the third for Ottawa's third power-play goal of the game.
Brian Elliott stopped 27 shots to win his third straight start, and Milan Michalek also scored on the power play in his return after missing seven games because of a concussion.
Brad Boyes scored 30 seconds into the third to draw St. Louis even at 2 after Eric Brewer scored the Blues' first goal late in the second.
Mason made 27 saves for St. Louis, which had won five of six.
Patrik Berglund, who did not dress for Wednesday night's 4-3 overtime win in Montreal, was back in the Blues' lineup as David Backes was sidelined by an upper-body injury.
St. Louis is 5-4-1 under coach Davis Payne, who took over behind the bench after Andy Murray was fired on Jan. 2.
Ottawa built a 2-0 lead midway through the second with a pair of power-play goals.
Regin, who has five points in his last two games, scored his second goal in as many games 16:09 in and assisted on Michalek's 17th goal 10:59 into the second. Alex Kovalev, who played his 1,200th regular season game, set up both power-play tallies.
Regin, who had a goal and an assist in Tuesday night's 4-1 win over Chicago, got credit for his eighth goal late in the first when Kovalev's centering pass went in off the Danish center's right skate.
David Perron scored an apparent tying goal for the Blues as time expired in the first. Referee Brad Watson pointed to the net to signal a goal although the green light signaling the end of the period prevented the goal judge from lighting the red light behind the net. A video review showed that time had expired before the puck crossed the goal line.
Michalek, who scored 9 seconds after Jay McClement was sent off for high sticking, returned to the Senators' lineup after missing seven games while recovering from a concussion. He suffered the injury in a 5-2 loss in Washington on Jan.
Brewer redirected Perron's shot from the right side into the net from the edge of the crease at 18:53 to draw St. Louis to 2-1.
NOTES: Blues RW Cam Janssen and Ottawa's Matt Carkner engaged in a lengthy fight 6:06 in. ... St. Louis wrapped up a 1-2-0 trip. ... Kovalev, who has also played for the New York Rangers, Pittsburgh and Montreal, has 406 goals and 570 assists for 976 career points.
