QUEBEC - Nick Merkley, Gage Quinney and Leon Draisaitl each scored twice as the Western Hockey League champion Kelowna Rockets downed the Rimouski Oceanic 7-3 Monday night at the Mastercard Memorial Cup.

Madison Bowey, who had two assists, also scored as Kelowna chased starting goaltender Louis-Philip Guindon in favour of Philippe Desrosiers at 10:42 of the second period after scoring five times on 22 shots. Kelowna outshot Rimouski 36-31 overall.

Chris Clapperton, Michael Joly and Frederik Gauthier scored for Rimouski (0-2), which has a must win game Wednesday night against the Quebec Remparts — the team it beat in the seven-game Quebec Major Junior Hockey League final.

The Rockets (1-1) end round-robin play against the Ontario Hockey League champion Oshawa Generals (2-0) on Tuesday night.

Kelowna scored three times in the opening 15 minutes, but the Oceanic answered with two before the end of the period.

The draft-eligible Merkley took a feed from Draisaitl, split the defence and beat Guindon with a backhand only 52 seconds in.

Bowey saw his point shot go in off Jan Kostalek's stick for an own goal at 6:16. And Merkley slipped the puck to Quinney out of a scramble to fire over a pileup in front of Guindon at 14:27.

Only 47 seconds later, after a faceoff in the Kelowna end, Clapperton score from the doorstep. Joly then went around the net, cut back in front and scored on a power play at 18:14 to make it 3-2 Rockets.

Quinney saw a shot sail over Guindon on a power play 1:52 into the second, while Merkley slipped the puck under the goalie on a drive to the net at 10:42 to restore the three-goal lead.

Desrosiers let in the first shot he faced when Draisaitl drove the net and fired in a Dillon Dube feed at 13:18.

Gauthier banked a puck in off a defender on a power play at 13:36 of the third only to see Draisaitl score shorthanded on and end-to-end rush at 14:16.

Merkley, who also had an assist, the undrafted 19-year-old Quinney and Edmonton Oilers 2014 first rounder Draisaitl each have three goals in two games.

Rimouski coach Serge Beausoleil opted to go with Guindon after Dallas prospect Desrosier gave up a bad rebound on Hunter Smith's game-winner in a 4-3 loss to Oshawa on Saturday.

The game drew the smallest crowd of the tournament thus far to the Pepsi Colisee, 6,981.
