Kempe scored on a one-timer on the power play to cut it to 4-3 at 16:28. He has seven points (five goals, two assists) in the past five games.
"We weren't really on our toes early," Kempe said. "I think that's something we've got to clean up and get better at, especially the last couple games. A good team will come from behind, but we have to learn to have a good start and play with a lead as well."
Rakell scored his second goal on a backhand in front of the net to push the lead to 5-3 at 18:15 of the second. Rakell, who had seven points (one goal, six assists) in the first 20 games this season, has 12 points (five goals, seven assists) in a six-game point streak.
"He's just slowly been chipping away at it," Eakins said. "Ricky was very, very upset. He takes it personally. He's got really high standards for himself and, for whatever reason, that puck wasn't going in the net for him early."
NOTES: Doughty had two assists to give him 400 in the NHL. ... Ducks forward Troy Terry left after the first period because of an upper-body injury, and defenseman Josh Manson left during the second period because of a lower-body injury. Eakins did not have an update on either player. ... Anaheim has scored at least five goals in each of the past two games after failing to do so in its first 24 games. … Ryan Getzlaf had the secondary assist on Rakell's first goal, his 699th in the NHL.
