Aho, who has five goals during a four-game streak, extended the lead to 4-2 at 1:03 of the third period. After Raanta stopped Svechnikov on a breakaway, Svechnikov got his own rebound and passed to a trailing Aho for a one-timer from the slot.
"[Svechnikov] is awesome to play with; he's got speed, he's got skill, he can score goals," Aho said. "I kept trying to find him and we tried to play fast hockey and skate to a lot of chances."
Conor Garland scored for the third straight game to cut it to 4-3 at 3:27.
"We got off to a good start, but we had mental lapses," Garland said. "We made some mistakes, but we fought back and gave ourselves a chance. We've just got to convert them."
Raanta stopped Svechnikov on another breakaway at 7:00 to keep it a one-goal game, but Aho scored into an empty net with 34 seconds remaining for the 5-3 final.
"Yeah, almost," Svechnikov said of just missing his first NHL hat trick. "I had so many chances to score, but the most important thing is we won the game."
