Great Britain are 31/10 to suffer Davis Cup defeat to Canada in the absence of Andy Murray in Ottawa this weekend.
Murray is taking a break after the Australian Open and the quartet of Dan Evans, Kyle Edmund, Jamie Murray and Dom Inglot are instead tasked with proving the team has strength in depth and securing victory at odds of 11/50.
Evans' heroics in reaching the fourth round of the Australian Open, beating Marin Cilic and Bernard Tomic, have elevated him into the world's top 50 and a ranking of 45 to Edmund's 47.
With world number three Milos Raonic having pulled out of the Canadian team with an injury suffered in Australia, the hosts do not have a top-100 player to call on in singles.
Edmund was the hero as Britain defeated Serbia last summer with Murray watching from the sidelines, while the last time they won a tie without the Scot present was in 2013 against Russia when Evans clinched the deciding point.
The hosts seem likely to field former world number 25 Vasek Pospisil, who has been woefully short of form since the start of last season, and 17-year-old Wimbledon junior champion Denis Shapovalov as their singles players.
Canada also have a strong doubles team in Pospisil and evergreen Daniel Nestor, who at 44 is playing in his 50th tie.
The odds are firmly in Great Britain’s favour despite the absence of Murray and captain Leon Smith said: “I'd imagine we probably would be favourites, but only just. You come to Davis Cup, we've had upsets before, we've had matches go against us with players that are lower ranked than ours - it happens.
“But what I do know is we've got a whole batch of experience across these four players now, they're very used to the environment of Davis Cup, they've been part of it for a very long time now, and all four of these guys will just go out and fight their hearts out.”
Great Britain are sixth in the betting at 11/1 to go all the way and lift the Davis Cup.
