DALLAS (AP) -- Derek Roy had a goal and two assists and Kari Lehtonen made 25 saves to help lead the Dallas Stars to a 4-1 victory over the St. Louis Blues on Sunday.
Loui Eriksson, Jaromir Jagr and Erik Cole also scored for Dallas.
For Cole, it was his first goal with Dallas in his second game with the team since he was acquired in a trade with Montreal last week.
The Stars also played impressive team defense, giving up just one goal after a deflating 5-1 loss at home against Edmonton on Thursday.
Lehtonen was strong after the Edmonton loss, which was his first game back after missing five because of a groin strain.
David Perron scored for St. Louis and Brian Elliott made 23 saves for the Blues.
The Blues lost for the first time in regulation in their past five road games (3-1-1) and are still 6-3-1 away from home.
Elliott was making his first start since Feb. 11, a span of eight games, after a 0-4-1 record with a 4.67 goals-against average since the beginning of February.
St. Louis appeared to tie the game at 2 at 8:59 of the final period, but it was waved off. After Lehtonen stopped Wade Redden's wrist shot from the left point, the rebound bounced off rookie Adam Cracknell's knee and was then directed into the net with his left skate.
Eriksson got his seventh goal at 10:28 to give Dallas a two-goal edge, firing a wrist shot from low in the left faceoff circle between Elliott's pads after receiving a nice cross-ice pass from Jordie Benn.
It was Eriksson's third goal in the past four games after getting just one in the previous 11.
The Blues pulled Elliott for an extra attacker with 2:56 remaining, but a hooking penalty on Perron with 2:04 left put Dallas back on the power play.
Jagr capitalized with his seventh of the season with 59.3 seconds to go, drilling a one-timer from in front after receiving a nice backhand pass from Roy behind the net.
The Blues jumped on top just 4:20 into the opening period on Perron's seventh goal of the season.
Seconds after a Jamie Benn giveaway in the Dallas zone, David Backes fed a cross-slot pass from the right faceoff circle to Perron, who made a nifty move to his backhand that faked Lehtonen to the ice as he stepped around him and tucked it inside the left post.
Before the puck even dropped for the ensuing faceoff, Dallas rookie Antoine Roussel challenged Chris Stewart to a fight in an attempt to fire up the Stars.
And while the Blues controlled play for much of the next 10 minutes, Roussel set up the equalizer at 15:59. His slick backhand pass from the right side of the crease found Cole in front for a one-timer that beat Elliott inside the left post.
Lehtonen kept the game tied with a nice save on T.J. Oshie's wrist shot from the left circle with 2:26 left in the first.
Later on the same shift, an Oshie giveaway led to Roy's third of the year with 1:40 remaining. Roy picked off Oshie's pass inside the St. Louis blue line, worked his way to the left circle and fired a wrist shot that burrowed its way through Elliott's right arm and dropped in for a 2-1 Dallas lead.
The Blues nearly tied it 2:42 into the second while on the power play, as Perron fired a wrist shot from the high slot that Lehtonen got enough of to deflect it just wide of the left post.
Elliott made a nice stop on Cole's point-blank wrist shot at 7:55 with Dallas on the power play.
Lehtonen then came up big with a nice pad stop at 12:55, denying Adam Cracknell's deflection in front.
NOTES: Stars rookie D Brenden Dillon was a physical force, delivering a game-high 11 hits while logging 25:03 of ice time, much of it against the Blues' top line. . Blues RW Adam Cracknell left the game with 7:12 remaining in the third period after crashing face-first into the boards during a collision with Stars D Jamie Oleksiak. He did not return. . The Stars honored Blues LW Jamie Langenbrunner, who played in Dallas from 1995-2002 and 2009-10, as part of the club's all-time team. Langenbrunner, who is out for the season with a hip injury, helped Dallas win the 1999 Stanley Cup.
