Saturday night was a first in the NBA in a couple of ways but a familiar sight in others.

For the first time this season, there were three triple-doubles on the same day:

- James Harden, Houston Rockets: 53 points, 16 rebounds, 17 assists

- Russell Westbrook, Oklahoma City Thunder: 17 points, 12 rebounds, 14 assists

- Malcolm Brogdon, Milwaukee Bucks: 15 points, 11 rebounds, 12 assists

Harden became the first player in NBA history with 50 points, 15 rebounds and 15 assists in a game, Elias Sports Bureau research shows.

Brogdon, a rookie out of Virginia, got his first triple-double, whereas Westbrook and Harden added to their totals.

Unprecedented performance caps productive month for Harden

With 53 points, Harden tied Wilt Chamberlain (in the 1967-68 season) for the most points in a triple-double and set a career high in all games (previous high was 51 points).

Harden also set a career high with nine 3-point field goals. That’s the most 3-pointers by any player in a triple-double (the NBA adopted the 3-point line in the 1979-80 season).

Saturday’s performance was Harden’s eighth triple-double of the season, and it marked the third time he has had them in back-to-back games.

Harden finished December with his fifth triple-double of the month. The five in December alone would be the most in one season in Rockets history entering 2016-17.

Through three quarters, Harden had 40 points, 13 rebounds and 13 assists. He is the only player in the past 20 years to have 40 points and 10 assists (much less the 10 rebounds, too) through three quarters.

Westbrook adds to his total

The triple-double tally for Westbrook is up to a league-leading 16 after Saturday, his first game after being ejected Thursday in a zero-assist game against the Grizzlies.

Westbrook got the triple-double in 23:26 of game time, beating his previous fastest mark, 23:49, against the Lakers on April 11, 2016.

Through 34 games, Westbrook is averaging 30.9 points, 10.5 rebounds and 10.7 assists.

Westbrook’s passes were especially effective. The Thunder finished 14-of-24 (58 percent) off passes by Westbrook, the third-best shooting percentage by Oklahoma City off his passes this season.

Brogdon thrives in rare start

Brogdon, starting for the second game in a row and the second time in his NBA career, is the first rookie with a triple-double since Elfrid Payton had one on March 20, 2015.

A second-round draft pick starting in place of injured Matthew Dellavedova, Brogdon had career highs in rebounds and assists, surpassing his previous career highs of six and eight. His 15 points are his second most in a game, behind the 17 he scored against the Wizards on Dec. 23.
