Oklahoma have one hand on the trophy after a win 120-109 over Indiana, whose star player Haliburton struggled in Game 5.
Jalen Williams erupted for 40 points as the Oklahoma City Thunder held off the Indiana Pacers to score a 120-109 victory and move to within one win of clinching the NBA Finals.
An enthralling Game 5 battle in Oklahoma on Monday saw the Pacers climb out of an 18-point first-half hole to get within two points of the Thunder in the fourth quarter.
But just as Indiana threatened the latest in a series of trademark comebacks, the Thunder found an extra gear with Williams and NBA Most Valuable Player Shai Gilgeous-Alexander steering the team to a pivotal victory.
The win leaves the Thunder 3-2 up in the best-of-seven series, meaning they can seal the NBA crown with victory in Game 6 in Indianapolis on Thursday.
