An NBA Championship ring awaits Australia’s Patty Mills and Aron Baynes if they can defeat the Miami Heat.

Patty Mills, Aron Baynes and their San Antonio Spurs are just one win away from claiming the NBA Championship.

The Spurs lead the Miami Heat 3-1 in the best-of-seven finals series.

Game five will be played in San Antonio from 10am on Monday (AEST).

“There’s still a long way to go,” said Mills, recalling how the LeBron James-led Heat came back from a 3-2 series deficit in last year’s finals to snatch the title from the Spurs.

“We still have a bad taste from last year.”

If the Spurs are victorious, Canberra’s Mills and Queenslander Baynes will join Luc Longley and Andrew Gaze as Australians with NBA Championship rings.

Longley won three consecutive championships with Michael Jordan’s Chicago Bulls from 1996 to 1998, while Gaze won his ring with the Spurs in 1999.

The Heat, thrashed by the Spurs in Miami the last two games, have refused to concede the championship despite history being against them.

No team in NBA history has recovered from a 3-1 hole in the finals to win the championship.

“Why not us?” James said.

“History is made to be broken, and why not me be a part of it?

“That would be great. That would be a great story line, right?”

If the Heat does win game five, the series will move to Miami for game six.
