Karlsson registered an assist, two shots and a minus-2 rating during Saturday's 8-3 loss to the Capitals.
Karlsson has two goals and five helpers during his six-game point spree. The 34-year-old could improve his minus-16 rating, but his point production has cemented him as a dependable fantasy rearguard. He has six goals and 39 points through 58 appearances this season.
