Warringah 22-20 Manly

Warringah prop Sateki Latu scored a hattrick to help his side claim victory and bragging rights in the 100th Northern Beaches derby at Manly Oval.

Manly led 10 nil early following a try from close range to prop and skipper Ivan Fepuleai and a penalty goal to Kemu Valetini.

But Latu quickly put his stamp on the match, scoring from a well worked play down the short side after an attacking lineout in the 28th minute, then again from close range just five minutes later.

Despite playing very little rugby in Manly’s half, the Rats led 12-10 late in the first half. However the Marlins hit back with a try from a driving maul on the stroke of half time and led 17-12 at the break.
