Canberra centre Jarrod Croker has capped off his 100th game in the NRL with a match-winning try and conversion against the Roosters at Canberra Stadium to lead his side to a 24-22 victory.
The Raiders fought back from a 16-0 halftime deficit to record the biggest NRL comeback in 2013.
The round five loss ended a three game winning streak for the Roosters.
Raiders captain David Shillington was inspirational for the home team, making 144 metres in attack and forcing several turnovers with his confrontational defence.
The Raiders’ handling skills began well below par once again, completing less than 50 per cent of their sets in the first half and leaving many of the 10,669 spectators less than impressed.
Their errors allowed the Roosters to race away to a 16-0 lead through tries to James Maloney, Michael Oldfield and Mitchell Aubusson.
The Roosters were just 35 minutes away from becoming the second team in rugby league history to win three consecutive games without conceding a point, when Croker sparked the comeback by throwing a flick pass to unmarked winger Edrick Lee.
The then Raiders grew another leg and earned back-to-back sets before halfback Sam Williams threw a dummy and wriggled his way over the line for the Raiders second try and an 18-12 deficit after 68m.
It took some magic from Roosters second-rower Sonny Bill Williams to stem the flow, splitting the Raiders defence before throwing a no-look pass to Anthony Minichiello who scooped the ball off his toes and dived over for the 55th minute try as the Roosters extended their lead to 22-12.
But the Raiders hit back again with just 15 minutes on the clock, Sandor Earl leaping above two Rooster defenders to snatch a Sam Williams crossfield kick to bring it back to a four point ball game.
Sustained pressure from the Raiders then saw Lee return the favour to Croker with a great no-look pass, giving the Raiders a memorable win.
