Vladimir Tarasenko scored at 4:20 of overtime to lift the St. Louis Blues over the Edmonton Oilers 4-3 on Friday night.
The Blues, who rebounded from a shootout loss to Ottawa at home on Tuesday, have won four straight against the Oilers and nine of 10.
The Oilers, who were beaten 1-0 in overtime in Nashville on Thursday, have dropped nine straight games, including three in overtime. They have also lost 13 of 15.
Tarasenko's goal was his team-high 13th of the season. T.J. Oshie had a goal and two assists for his first multipoint game of the season. Jake Allen made 13 saves.
Edmonton's Ben Scrivens stopped 37 shots in the loss.
Oshie's second goal of the season, a drive from beyond the right circle after a drop pass by Tarasenko, beat Scrivens high stick side and gave the Blues a 1-0 lead with 8:25 remaining in the first period.
The Oilers went nearly 10 minutes in the first without a shot and had just three shots in the period, but they tied the game on David Perron's third goal of the season with 14:09 left in the second period.
Perron has two goals in four career games against his former team. He scored 84 in six seasons with St. Louis before being traded before the 2013-14 season.
Edmonton went ahead 2-1, its first lead since beating the Rangers on Nov. 9, when Nikita Nikitin scored off a back-door assist from Taylor Hall with 3:14 remaining in the second.
Kevin Shattenkirk tied it 2-2 with a long shot from near the blue line, assisted by Oshie, just 31 seconds into the third.
Mark Arcobello put Edmonton back in front 3-2 three minutes later with his fifth of the season off another nice pass from Hall.
The Blues tied it with 7:35 remaining when Alex Pietrangelo put in a rebound of Oshie's miss.
