Ireland were backed at the lowest odds possible on the Betfair Exchange when going ahead against Japan, but the hosts rallied to pull off a shock win
"Ireland's World Cup winner odds have taken a sharp rise, and they are 15.014/1 to be the last team standing. Japan are 90.089/1."
Ireland suffered a major World Cup embarrassment when going down to a dramatic defeat to hosts Japan today.
Joe Schmidt's side were hot favourites to win their second game of the tournament and went off around 1.11/10 to win the game.
Those odds shortened to Betfair's lowest price of 1.011/100 after a Rob Kearney try halfway through the first 40 minutes.
Japan were accordingly written off by Betfair layers, going out to 70.069/1 in-play on the Exchange.
But it was a flat performance from the Irish and a pair of Yu Tamura penalties kept the Brave Blossoms in the game, with the score sitting at 9-12 at the break.
Japan, who beat South Africa to pull off the major upset of the 2015 World Cup, went ahead midway into the second half and the expected Irish fightback never materialised. A late penalty from Tamura took the hosts to a seven point lead which Ireland did not manage to close.
The result leaves Group A wide-open with Ireland, Japan and Scotland all in with a chance of topping the group. Ireland have been backed at 1.031/33 to head up the quintet of teams vying for top spot.
