Carlisle United are narrow favourites to turn the tables on Leyton Orient at Brunton Park this afternoon.
The Os did the double over the Blues en route to the League Two title last season - including a stormy 3-2 win in Cumbria.
But Paul Simpson's side have the shorter victory odds today, with United priced 8/5 with Unibet for the win, 6/4 with 888Sport and 7/5 with BetVictor to prevail against their fellow promoted side.
Richie Wellens' men are 9/5, 15/8 and 17/10 for victory with the same bookmakers.
The draw at Brunton Park is 12/5.
Carlisle's Jordan Gibson was the Blues' hero in their last league outing at Bolton Wanderers, and the attacking midfielder is 12/1 to open the scoring this afternoon, and 9/2 to find the net at any stage in the game.
A second consecutive hat-trick for Gibson, meanwhile, is 500/1. Not since Karl Hawley against Stockport County and Torquay United in 2005 has a Blues player registered trebles in back-to-back league games.
Sean Maguire is 15/2 favourite for the opener, with Joe Garner and Luke Plange 8/1.
For the Os, Joe Pigott is 8/1 to score first, with Ruel Sotirou 9/1 and Theo Archibald - a two-goal scorer in this game last season - 12/1.
Longer shots for the first goal from a Blues point of view include Owen Moxon at 13/1, Alfie McCalmont at 16/1, Jon Mellish at 22/1 and Fin Back at 22/1.
United have to go back eight games for their last home win over the Londoners, a 4-1 victory under Greg Abbott in January 2012.
A repeat of that scoreline is 75/1 while another memorable home victory, a 6-1 triumph back in 2002, is 350/1 to be emulated.
More orthodox home victory prices include 1-0 at 15/2 and 2-1 at 9/1.
Orient are 35/1 for a second consecutive 3-2 win at United's ground while a 2-0 away win is 14/1.
A goalless draw is priced 10/1 with odds of 11/2 on offer for a 1-1 draw.
