He finished with 18 points, 14 assists and 11 rebounds behind 6-of-6 shooting from the field and 6-of-6 shooting from the free-throw line. Royce Young of ESPN.com noted he became the first player in league history to notch a triple-double without missing from the floor or charity stripe.
Westbrook didn't attempt a three-pointer during the game, which is notable because he is shooting an uninspiring 33.6 percent from deep this season.
He said he worked for better shots, per Young: "[I] watched some film and just [tried] to pick my shots better, find ways to get my teammates involved throughout the game. Just happy to win."
Wednesday brought plenty of firsts for the six-time All-Star. According to Young, it was the first time Westbrook didn't miss a shot from the field and the first he didn't shoot from downtown in 83 games. And his six field-goal attempts tied a career low for games in which he's played more than 20 minutes.
Westbrook's triple-doubles have been one of the marquee storylines of the season, and Wednesday marked his 35th in 2016-17 and the 72nd of his career. It was also his fifth career triple-double against Philadelphia, the most for any opponent, per Young.
He is on pace (31.2 points, 10.5 rebounds and 10.4 assists) to join Oscar Robertson and become one of the only two players in NBA history to average a triple-double throughout an entire season.
Westbrook and the Thunder have just 11 games remaining and face teams with winning records in only four of them. That means the point guard will have plenty of opportunities to rack up formidable stats and improve his team's playoff standing against vulnerable opponents, as he did Wednesday versus the 26-45 76ers.
Whether averaging a triple-double for an entire season lands him the MVP award remains to be seen, but he has chances to make statements in the near future, with head-to-head showdowns against fellow candidates James Harden (Sunday) and Kawhi Leonard (March 31).
