Canberra coach Tim Sheens didn't know whether to laugh or cry after the Raiders crushed North Queensland by a record 66-10 yesterday in the Australian Rugby League premiership yesterday. In his role as Raiders coach, Sheens was delighted to post his first win of the year in such devastating style. But looking ahead to next year, when he will take over as coach of North Queensland, Sheens must have been disappointed by the Cowboys' inept showing. 'We were desperate for a big win today and came out meaning business,' Sheens said. 'We would have thrashed anyone - the team was determined to play well after some poor displays in recent weeks.' Rampaging centre Ruben Wiki led the way for the Raiders, running over the top of his opposites to score four tries. Veteran Phil Blake, playing at hooker for the first time in his career, led Auckland to a 12-8 win over previously unbeaten North Sydney. Coach John Monie's gamble to move Blake into the pack paid a handsome dividend for the Warriors as they played their best football for many weeks. Blake created havoc with his probing runs from dummyhalf, constantly gaining valuable ground up the middle of the ruck. The Bears' loss has left Sydney City on top of the premiership, the only undefeated team after four rounds. The Roosters were in awesome form at home, crushing Penrith 30-14. Test skipper Brad Fittler, playing against his old side for the first time, starred for the Roosters, while centre Peter Clarke scored two tries. St George continued its recent revival with an impressive 26-6 win over Canterbury to sour the Bulldogs' return to Belmore Oval. In their first match back 'home' in nearly 15 months, the Bulldogs were totally outplayed in all areas and are still without a win from their four games. The Sydney Tigers produced the upset of the round, downing Newcastle 24-12 at the Knights' home ground Marathon Stadium. Manly struggled to a 10-6 win over Gold Coast in a dour match.
