For years, the Bruins won despite a power play that was hardly an advantage.
But as this season has gone along, the Bruins have climbed higher in the power-play rankings, getting closer to the top of the league. In fact, they began Friday ranked fifth, scoring on 22 percent of their chances.
They converted again against the Senators, and now have five in their last three games. For the season, they are 23 for 102 (22.5 percent).
Jarome Iginla got the tally on Friday, the first goal of a game that the Bruins went on to win, 5-0, at TD Garden in the first game of a back-to-back with the Senators.
After Torey Krug fired in a shot on net, the puck bounced off Milan Lucic to Iginla, who nabbed his second power-play goal in as many games. Iginla now has six goals and nine points in his last nine games. Full story for BostonGlobe.com subscribers.
