The defending Stanley Cup champion Capitals got faster ahead of the NHL trade deadline by acquiring speedy winger Carl Hagelin from the Kings on Thursday.

The Caps sent a 2019 third-round pick and a conditional 2020 sixth-round pick to the Kings.

Hagelin must satisfy a games-played requirement in the playoffs and the Capitals must win two rounds for the Kings to get the sixth-rounder in next year’s draft.

The teams announced the trade after Caps winger Devante Smith-Pelly cleared waivers and was assigned to Hershey of the AHL. The Capitals needed to wait until Smith-Pelly was claimed or cleared waivers to clear a roster spot and salary-cap space for Hagelin.

Hagelin had just two goals and six assists in 38 games this season with the Penguins and Kings.

The Ducks and F Jakob Silfverberg agreed to a five-year extension worth an average of $5 million per year, according to reports. Silfverberg, 28, has 16 goals and 24 points in 51 games. ... The Coyotes signed D Jordan Oesterle, 26, to a two-year extension. News services
