Warringah and Norths both claimed tight wins over their arch rivals, while Uni Eastwood and Easts took the points in their respective clashes.  Hear what the coaches had to say after their round eight matches played over the weekend.  Warringah 31-25 Manly Thousands of Marlins fans were left shellshocked at Manly Oval after they watched bitter rivals Warringah score 28 unanswered second half points to claim arguably the most memorable Battle of the Beaches victory in recent times.  The home side looked to be in complete control after leading 22-3 at the break thanks to a double to young winger Ben Howard and a third try to lock Alex Humphrey.  Manly extended their lead with a penalty goal early in the second half, before momentum swung to the visitors.  The Rats scored back to back tries to reduce the deficit to one point, then stole victory when Boyd Killingworth showed the pace he’s picked up from Sevens and linked with Josh Holmes to score the match winner.Â
