Huddersfield Giants turned the Super League table on its head with a 31-12 win over Leeds Rhinos at Headingley.
The Giants came into Thursday's game licking their wounds from an embarrassing Challenge Cup defeat to Swinton, but coach Rick Stone was given a fine response as second-bottom beat second back in league action.
Before the game, only Widnes had conceded more points than Huddersfield, but a staunch rear-guard was to thank for victory as the Giants won the second half 19-0 to hand Leeds a first home defeat in nine months.
Matt Parcell had put Leeds ahead against the run of play with his eighth try in eight games, but Jake Mamo hit back for the Giants after sneaking onto Alex Mellor's neat grubber and Kruise Leeming set himself up with an excellent 40-20 to crash over and put Huddersfield ahead.
Stevie Ward got Leeds back on level terms before the break, but the hosts fell apart in the second half.
Dale Ferguson put the Giants back in front and the lead was extended further as Danny Brough's kick spiralled to a stop in the in-goal area, leaving teenage sensation Jack Walker the tricky task of running the ball out deep from his own territory. Though Walker initially got things clear, Ryan Hall's poor pass put Huddersfield back in control and Darnell McIntosh raced over.
Brough's drop goal left Leeds requiring three scores but Oliver Roberts extended the advantage even further to delight the travelling support - Brough ending a superb night on a high with a fifth successful kick from as many attempts.
