Canberra have put a dent in the Sydney Roosters' NRL minor premiership aspirations with a 14-12 upset victory.
The Roosters could have gone a game clear on top of the ladder with a win at GIO Stadium but their poor record in the nation's capital continued, where they haven't won since 2010.
The Roosters are locked in a three-way battle at the top of the table for the minor premiership with Melbourne and South Sydney.
Trent Robinson's team had a chance to score in the final minute as they charged in attack, but a knock-on turned the ball over to see the Raiders home and reverse their 2018 fortunes in close games.
Unlike most matches featuring the Raiders this season, defence reigned supreme as Ricky Stuart's team held the Roosters scoreless in the first half.
The Raiders led 12-0 at the break thanks to an early try for winger Jordan Rapana before halfback Sam Williams slotted three penalty goals in windy conditions.
But the Roosters were never going to wilt as captain Boyd Cordner found a gap in a sleepy Raiders defence just a few minutes into the second half.
Roosters lock Victor Radley levelled the scores with a diving try in the 60th minute, but the Raiders weren't done as Williams put his team back in front with another penalty goal.
That's where the score would stay as the Raiders secured their ninth win of the season and maintained their position in 10th on the ladder but are out of the finals race.
The Raiders had to deal with Luke Bateman and Brad Abbey going off for head injury assessments, forcing five-eighth Blake Austin to move to fullback.
Raiders coach Ricky Stuart says the victory contained "plenty of heart".
"Still with players out and the way they rallied around and played for each other, they played some really good football," Stuart said.
"If you complete your defence it's a little bit easier to execute. We actually played well tonight and that was the pleasing factor."
Roosters coach Trent Robinson says his team has plenty of work to do before the finals.
"We've been in front a lot, we were behind today, it hasn't happened for a while," Robinson said.
"We fought our way back into the game really well and came out after halftime clear about what we wanted to do, but we just couldn't sustain it."
