FINALS smokies the Panthers have booked their place in next Saturday's semi-final against Canberra at GIO Stadium after they snuffed out Canterbury's season 28-12 at Allianz Stadium.

Down 6-4 at half-time, Penrith produced three second-half tries, including the try of the finals series after skipper Matt Moylan combined brilliantly with winger Josh Mansour before makeshift centre Tyrone Peachey and then Issah Yeo set up elated veteran Peter Wallace to cross.

Peachey scored eight minutes later for a 24-6 lead, which the Bulldogs, who have been struggling for points in recent weeks, were never going to pull back

An animated Bulldogs coach Des Hasler - contesting his 12th consecutive final series - ripped into his players during the half-time break, laying the law down but Penrith never let them into the game after Waqa Blake scored three minutes after the resumption.

Man-of-the-match Mansour capped off a tremendous Panthers victory with a 75th-minute try.

Canterbury's frustration became evident late in the second half when halfback Moses Mbye singled out hooker Michael Lichaa, screaming in his face that he wanted the football more.

Dogs winger Sam Perrett signed off his long career by converting his 78th-minute try.
