Jack Welsby's last-gasp try saw St Helens defend their Super League title in remarkable fashion in a low-scoring 8-4 victory over rivals Wigan Warriors at the KCOM Stadium.

Saints had tied things up late on in Hull through Lachlan Coote's penalty after Jake Bibby had scored the first try of the game for Wigan in the 66th minute.

Zak Hardaker missed a penalty of his own for Wigan and drama ensued when Zak Makinson's drop-goal for Saints hit the post.

Welsby reacted quickest to the rebound to score for Saints, who had peppered the Wigan tryline in the first half but led just 2-0 at the break, to make it back-to-back Grand Final triumphs.

It means veteran James Graham retires on top in the first Grand Final held away from Old Trafford, but for legendary Warriors star Sean O'Loughlin it was a heart-breaking end to a fine career.

Wigan, League Leaders Shield winners, have now lost three of the four Grand Finals they have played against their fierce rivals.
