What was supposed to be the first step to back-to-back championships turned into a nightmare for the Golden State Warriors.

The Oklahoma City Thunder took game one of the NBA’s Western Conference Finals after they defeated the Warriors on Monday in Oakland, 108-102, at Oracle Arena. It was the first home loss in the playoffs for the Dubs and just the third loss at home this season.

It was also the first time Oklahoma City won a game in Oakland since 2013, that was over 3 years ago.

The Warriors maintained a commanding lead throughout the game, and even led by as many as 14 points in the fourth quarter. However, it was the Thunder duo of Kevin Durant and Russell Westbrook that took over the fourth quarter and not the splash brothers.

Warriors center Andrew Bogut went out of the game with an injury in the final period, and the Golden State ball movement slowed as well, which allowed the Thunder to push the ball and score on the fast break.

“We need to move and create rhythm with our screening and our cutting,” Kerr said during his press conference after the loss.

“We took too many quick ones that took us out of our rhythm.”

Westbrook was held to just 3 points in the first half, but exploded for 24 in the second. Durant chipped in with 26 points of his own, including two huge ones on a jumper with just over 30 seconds left to put the Thunder up by 5.

“There’s a lot of basketball to be played so we can’t be too excited,” Durant said during a press conference following the game.

“It was a good win for us but we’re not going to be jumping up and down chest bumping on the court, we got a lot more basketball left to play.”

Defensively, the Warriors were fine through the first three quarters and then things began to break down. Westbrook’s 19 fourth quarter points are the most allowed to any player in any quarter this season for Golden State.

Westbrook, Durant and big man Enis Kanter all gave the Warriors matchup problems with their size and athleticism.

The two-time MVP Stephen Curry had an off shooting night and was 9-for-22 from the floor and 6-for-12 from behind the three point line. The entire team had a tough shooting night, making just 40 percent of their shots in the game. Curry and the other half of the splash brothers, Klay Thompson, combined to score 51 of Golden State’s 102 points and forward Draymond Green also factored in with 23 points of his own.

Last night was game 2 of the series at Oracle Arena in Oakland.
