Lakers star Russell Westbrook was ejected from Wednesday night's game against the Thunder when he became irate over what he apparently saw as a violation of some sort of unwritten rule.
The scene unfolded in the game's final seconds, with OKC owning a comfortable 5-point lead.
Thunder forward Darius Bazley stole a Lakers inbound pass and slammed it home on a wide-open breakaway dunk, stretching the lead to 7 points with 1.5 seconds remaining.
Westbrook immediately confronted Bazley, and appeared to repeatedly tell him "Don't do that." Players on both teams gathered to separate them. No punches were thrown, and shoving appeared to be kept at a relative minimum.
Westbrook was assessed a technical, his second of the game after a prior hard foul on OKC's Shai Gilgeous-Alexander, who sank a technical free throw for the final 8-point margin of victory.
After the game, Westbrook said he was "old school" and added that he doesn't "let it slide" when the unwritten rules of sportsmanship are breached.
Bazley's dagger play capped a brutal collapse for the Lakers, who outscored the Thunder by 22 points in the first quarter and at one point in the game stretched their lead to 26 points.
Bazley could have simply dribbled out the clock to end the game, which seems to be the crux of Westbrook's gripe.
Perhaps Bazley was lost in the moment or maybe he just wanted to pad his stats, but Westbrook certainly didn't appreciate his emphatic display.
Interestingly, he seemed to liken the play to baseball's bat-flipping craze.
"In the game of basketball, there's certain things you just don't do," Westbrook said. "Like in baseball, you don't flip the bat. ... The game was already over, and I didn't like it."
