Jordan Spieth has insisted that he is only thinking about producing a perfect performance in the new format of the WGC-Cadillac Match Play Championship.
A knockout event has been replaced with 16 groups of four, and the players will compete in a round-robin format to decide who reaches the last 16 in San Francisco.
It means that a player can still qualify for the knockout stage with a loss to his name, but Spieth believes that a 100% record could prove to be crucial.
"I don't think the change in format does anything," the world number two told reporters. "It's still pretty much win or go home.
"You certainly have a chance to get lucky if you lose one, but our mindset can't be like that. You have one extra match to play in order to win the championship and most likely you are going to have to win all three of your matches in pool play.
"You don't really want to go to a play-off and you don't want to lose and rely on that guy not losing the next two so you don't get the [better] head-to-head record. In my mind it's win or go home."
Spieth will take on Lee Westwood, Matt Every and Mikko Ilonen in the first round.
