Mariners 29 Renegades 7 In the biggest upset in recent memory, Mariners showed a huge commitment against a previously unbeaten Renegades team.

This was by far Mariners' best performance in years. Gades had to field a weakened front five with the result that their attacking back row of Shane Gill and Rod Stewart were ineffective.

But Mariners' commitment and skill in the rucks and mauls was quite something as Steve Robb and Greg Brookes proved effective in the tackle and in winning the ball on the ground.

For Gades, full back Colin Targett came into the line well on a number of occasions but was found wanting in defence where he failed to field several testing kicks from Dave Conway and Josh McGavern.

Mariners applied all the pressure in the first half and were rewarded by tries from McGavern and Simon Hurstenstein who sliced through three defenders with blistering speed for a converted try to give them an 18-0 lead at half-time.

The scrums were a shambles, most collapsing because of weak tight head props on both teams, in particular Des Nash for Renegades who was given a torrid time by Andy Creighton.

In the second half, Keith Hodgkins increased the lead to 24-0 by slotting over three penalties, all from Renegades offside offences.

Renegades eventually woke up with 20 minutes remaining and came close to scoring on a number of occasions, but there were too many dropped passes.

Gades centre Greg Garside was stopped from scoring a sure try by a Conway ankle tap.

Robb then put the final nail in the Renegades coffin with a superb try after Hurstenstein had broken through the defence. Gill crashed over for a consolation try in injury time.

Mariners now face Teachers in two weeks' time.

Teachers 62 Police 27 In the highest scoring match for several seasons, Teachers finally clicked.

They came out of the changing rooms firing on all cylinders and were 17 points up after 15 minutes following tries from Freedom Burrows and then two from Heath Robinson in less than a minute.

Police never gave up and struck back with a try from Chris Weddon, playing in only his third first XV match.

However, the Reds onslaught continued with another fabulous try from Burrows after Robinson had come into the line from blind side wing and carved a hole in the Police defence. Alvin Harvey and Scott Correia supported the movement before handing off to Burrows to crash over.

Patrick Cooper won a race to the try line and Anthony Cupidor crossed after a superb 50-metre break by Nathan Brown to push the score to 36-7.

Teachers sat back in the final 10 minutes of the first half and Dave Bird cut the difference to 36-13 at half-time with two penalties. Police actually took control at the start of the second half and Gareth Davies and Bird scored tries in a brave comeback that brought them to within nine points of Teachers.

Then Teachers substituted Billy McNiven and Burrows with two fresh props in Tim White and Brian Desmond and this changed the course of the game, resulting in a demoralising 25 minutes for Police with their pack being driven backwards. The abundance of good ball gave the Teachers backs a chance to shine and resulted in four more tries from Harvey (two), Bobby Hurdle and Peter Rochow.

In the only Second XV match played, Mariners edged Renegades 8-0. Police were unable to field a second XV for the third week.

There are no league matches this weekend.
