Only something special in his 18th Origin it seemed would keep Jennings in the NSW mix for next year.
He left it late - but he made made it count.Jennings crossed with 78 seconds left after a long James Tedesco run from a Blake Ferguson break, providing some consolation for his game-two shocker.
"To get that win is an awesome feeling," said Jennings who made 127m and had one line break.
"I am grateful for the opportunity.
"I was fortunate enough to get there in the end."It means a lot - we'll go into next year with a positive attitude."
Queensland looked set for a fifth series whitewash when fullback Darius Boyd crossed in the 75th minute to give the visitors a 14-12 buffer.
However, Jennings went from zero to hero by crossing in the 79th minute in front of 61,267 mostly delirious NSW fans.
"It's a miracle try," Nine Network commentator and former NSW coach Phil Gould beamed.
