The Dallas Stars teammates joined Paul Coffey and Charlie Huddy as those to accomplish the feat. Coffey and Huddy did it with the Edmonton Oilers during the 1985 playoffs when they recorded 37 and 20 points, respectively.
Klingberg's goal in the opening frame of Game 4 of the Stanley Cup Final helped him reach the 20-point mark, while Heiskanen already had 24 points entering the contest. They've each appeared in 25 games this postseason, including Dallas' three contests in the round robin of the qualifying round.
The pair are leading the way for the Stars this postseason, with Heiskanen sitting at No. 1 and Klingberg second in team scoring.
