Kawhi Leonard scored 31 points as the San Antonio Spurs took the series lead with a 100-96 over the Oklahoma City Thunder on Friday.

How big of a game was this? Had the Thunder won, ESPN's Basketball Power Index would have projected them to be slight favorites to win the series (53 percent). However, now down 2-1, their odds of winning the series have dropped to just 17 percent.

Here's a look at how the Spurs won Game 3:

Kawhi takes over late

Leonard scored a game-high 13 points in the fourth quarter. Leonard also took care of business on the defensive end, spending the majority of the final quarter covering Kevin Durant.

Leonard defended Durant on 62 percent of the Thunder's possessions in the fourth after guarding him on only 13 percent of possessions over the first three quarters. Durant was 1-of-4 when guarded by Leonard in the fourth quarter and went 2-of-2 when guarded by anyone else.

The Thunder offense sputtered when Leonard guarded Durant in the fourth quarter. While the Thunder went 6-of-8 from the field as a team whenever Leonard ended a possession on anyone else, they went just 5-of-13 on possessions Leonard ended on Durant.

Thunder can't capitalize when left open

The Thunder didn't get many open looks in Game 3 as the Spurs contested 75.6 percent of the Oklahoma City's shots.

Even when Oklahoma City could get an open look, it failed to knock shots down with regularity. The Thunder were 8-of-20 on uncontested shots, and the 40 percent is the second lowest they have shot on open looks in these playoffs. Oklahoma City shot 37.9 percent when uncontested against the Mavericks in the Game 2 loss.

'Old' Spurs outrun Thunder

The Spurs outscored the Thunder 26-17 in transition in Game 3, their most such points in these playoffs.

Six of those transition points came in clutch time, including two off a Russell Westbrook turnover with less than two minutes left and the Spurs up three. Clutch time is defined as five minutes or less to play with the score within five points.

Westbrook scores but ...

Westbrook also scored 31 points, tying Leonard for the game high. But Westbrook needed 31 shots to do it, 14 more than Leonard.

Twenty-one of Westbrook's shots were when he started and ended a possession without passing, most in the playoffs this season. He made only five of those shots and all but two were contested.

It was the 33rd time that both Westbrook and Durant scored 25 points in a playoff game, which tied with Shaquille O'Neal and Kobe Bryant for second-most such games by an NBA duo. Only Elgin Baylor and Jerry West have accomplished the feat more times, doing so on 50 occasions.
