VIDEO: Spurs' Kawhi Leonard soars for ridiculous NBA Finals Game 4 dunk

The San Antonio Spurs forward had the play of the game in the 107-86 win over the Miami Heat.

Kawhi Leonard stole the show with a vicious put-back slam at the end of the second quarter as the San Antonio Spurs crushed the Miami Heat for the second consecutive game to take a 3-1 Finals lead.

The dunk punctuated a first half performance which saw the Spurs build a 55-36 lead. The Heat were bewildered by San Antonio's rapid ball movement, dominant rebounding and stifling defense, and the two-time defending champions were even booed at times by their home fans.

The slam sits alongside Russell Westbrook's emphatic jam in Game 5 of the Western Conference Finals and Leonard's posterization of Serge Ibaka in Game 6 of the same series as the best dunks of the playoffs.

Leonard has been the Spurs' shining star in the past two games, leading the team in scoring with 28 points in Game 3 and then 20 in Game 4, and he may be on the way to winning an unlikely Finals MVP award. He has played excellent defense on LeBron James, and at the age of just 22 he has the potential to be one of the biggest stars in the league for years to come.

The Spurs, who came so close to beating Miami to the title last year, look unstoppable on current form. The Heat, on the other hand, are completely out of sorts and are clearly fatigued after making their fourth Finals trip in as many years.

LeBron James tried to take it upon himself to get the Heat back into the game. He scored 19 of his team's 21 points in the third quarter but got little help from his supporting cast, and the Spurs pulled away again to seal the big victory.
