St Helens 16 Tries: Graham, Gidley, Gardner Goals: Long 2
Leeds Rhinos 24 Tries: Smith, Hall, McGuire 2 Goals: Sinfield 4
Come into this game, Saints were overwhelming favourites as they had not lost a game since April and got off to the perfect start when James Graham finished off a following move.
Underdogs Leeds hit back in style with a Lee Smith try thanks to a good pass from Jamie Jones-Buchanan. Just before the break Ryan Hall -who was only playing because Kiwi Full-back Brent Webb was ruled out due to a back injury-kicked through to score as the Rhinos went into the interval with a 12-6 lead.
Matt Gidley drew Saints level just after the break but again the Headingley outfit responded with a Danny McGuire try, after a deft kick from Skipper Kevin Sinfield. Ade Gardner squeezed into the corner as St Helens cut the gap to 18-16.
St Helens threw everything at Leeds but their scrambling defence held out and McGuire pounced on a Francis Meli mistake to clinch a memorable win.
Leeds will now look forward in taking on NRL premiers Manly Sea Eagles next year for the World Club Challenge.
