The record breaking Golden State Warriors are just one loss away from being bundled out in the Western Conference Finals.
Oklahoma City Thunder recorded a thumping 118-94 win over the Warriors, to claim a 3-1 series lead and put them just one win away from reaching the NBA Finals Series.
The Warriors recorded the greatest ever regular season in NBA history. However, they were made to look second rate, as the Thunder won Game 4 in a canter.
It is the first time the Warriors have suffered back to back losses this season.
Two-time MVP Steph Curry could only manage 19 points, while Draymond Green finished with just six points and 11 rebounds.
Russel Westbrook finished with 36 points, 11 rebounds and 11 assists, while Kevin Durant scored 26 points.
The Warriors were never in the match, as the Thunder opened up 22-8 lead early in the game, after scoring 16 consecutive points.
They opened up a 19-point lead at half time (72-53), as Westbrook had 21 points by the main break.
The Warriors then managed 19 points in a row in the third to get within eight, but it was to no avail, as the Thunder proved too strong, pulling away again in the final term.
Game 5 is at Oracle Arena on Wednesday.
