The NBA has fined Oklahoma City Thunder guard Russell Westbrook $15,000 for “inappropriate language” during his postgame media session on Wednesday, the league announced.

Westbrook posted a triple-double with 51 points, 10 rebounds, and 13 assists in the Thunder’s 115-111 loss to the Houston Rockets in Game 2 of the first round of the Western Conference playoffs. Oklahoma City has now fallen to 0-2 in the series.

When asked about his stat line, Westbrook responded, “I don’t give a f— about the line, we lost.”

Wins and losses have been the sticking point all season for Westbrook, who broke Oscar Robertson’s regular season triple-double record and became just the second player to average one in NBA history this year. His play helped guide the Thunder to a 47-35 record, good enough for the Western Conference’s sixth seed.

He scored 51 points on Wednesday but took questionable shots in the fourth quarter as he shot 4 of 18 from the field. The series now shifts back to Oklahoma City for Games 3 and 4.
