Henrik Samuelsson's first career hat trick helped the Edmonton Oil Kings take sole possession of first place atop the Western Hockey League's Central Division.
The Oil Kings beat the Brandon Wheat Kings 6-2 on Monday and moved three points clear of rival Calgary after the Hitmen fell 3-2 to Kootenay.

At Edmonton, Moroz opened up the scoring for the Oil Kings at 10:30 of the first period, taking the puck just inside the left faceoff circle and wiring it above the glove of Brandon netminder Corbin Boes.
Samuelsson doubled Edmonton's lead 1:14 later, streaking in on the right wing and beating Boes to the blocker side.
McGauley pulled Brandon back within one with 3:18 remaining, corralling a rebound off Oil King netminder Laurent Brossoit's left pad and tucking it home.
Lowe restored Edmonton's two-goal margin at 2:56 of the second, letting loose a cannon from the point through traffic to make it 3-1 Oil Kings.
Samuelsson added his second of the game at 8:48, finishing off a goalmouth scramble from a sharp angle to put Edmonton up by three.
Lowe and Samuelsson's third period power-play goals put the game out of reach for Brandon before Nejezchleb's late goal with 3:38 remaining.
