Sydney University v Randwick at University Oval No.1
A 43-point second half from Sydney University has delivered the four-time defending champions a 55-22 victory over Randwick at University Oval No.1.
While Randwick may have gained some revenge for their 2008 Grand Final defeat with victory in round seven, Uni wrested back the advantage with a comprehensive display which saw the Students run in six second half tries including a hat-trick to Nathan Trist.
The Students taught a lesson of their own in turning opportunity into points, with four of their eight tries directly eventuating from Randwick mistakes.
The visitors opened the scoring on the back of a rare tighthead scrum win, with the ball spread quickly to Tim Wright who used good speed and evasive skills to cut back and score under the posts in just the fourth minute.
Daniel Halangahu laid on the Students first try in the 23rd minute when he put Tim Davidson into a gap at close range, with the conversion tying up the game.
Less than a minute after the restart Dave Parsons juggled a ball which was intercepted by Davidson and offloaded to Tom Carter for a 45m run to the line. Halangahu missed the conversion leaving the margin at five.
As the clock wound down before half-time, Marshall Milroy piloted a penalty from in front to close the gap to two, which is how the teams went to the break.
However the narrow margin was short-lived upon resumption when confusion at the back for Randwick resulted in Pat McCutcheon enjoying an open run to the line after just 40 seconds of play. Halangahu converted and kicked another penalty soon after for a 22-10 lead.
Another try against the run of play followed in the 50th minute when Dave Dennis intercepted near halfway and streaked away to score untouched to earn the bonus point.
Milroy showed a piece of individual brilliance to step and accelerate through the line, crossing 15m in from touch but failing with his conversion attempt.
The points kept coming, and again the Students capitalised on a Randwick mistake when Tony Luxford juggled a high ball into the arms of Nathan Trist who ran 20m to score. Halangahu's conversion took the score to 36-15, and 29 points had been scored in the first 17 minutes of the second half.
Jacob Taylor was next to cross for the Students after outpacing Dave Dillon from his own grubber kick, neatly regathering to score in the left corner.
Trist crossed for his second try of the match with less than ten minutes left on the clock after backing up another line break from Uni captain Davidson. Halangahu's conversion stretched the lead to 48-15.
Randwick kept trying in hope of a bonus point and Tim Walsh scored five minutes from full-time with an individual try under the posts, however the only remaining touchdown went to Trist who scored his hat-trick to take his season tally to 19 tries.
Sydney University 55 (Nathan Trist 3, Tim Davidson, Tom Carter, Pat McCutcheon, Dave Dennis, Jacob Taylor tries; Daniel Halangahu 5 cons, pen, Scott Stumbles con) d Randwick 22 (Tim Wright, Marshall Milroy, Tim Walsh tries; Marshall Milroy 2 cons, pen) at University Oval No.1. Referee: Steve Walsh. HT: Sydney University 12-10.
Manly v Northern Suburbs at Manly Oval

Gordon v Eastern Suburbs at Chatswood Oval
Dave Harvey showed some of the brilliance which earned him the 2008 Ken Catchpole Medal by kicking the match-winning drop goal in Gordon's 22-21 victory over Eastern Suburbs at Chatswood Oval.
In a match which could not have been tighter, the scores were locked up at half-time before Easts established a narrow lead going down the stretch.
However with the visitors up 21-19 as the clock wound down, Harvey slotted the timely three-pointer for the win which lifts Gordon above the Beasties on the Tooheys New Shute Shield ladder.
