It is both amazing and now seemingly routine in nature.

Houston Rockets guard James Harden had another 40-point triple-double on Tuesday in a win over the Charlotte Hornets.

The Rockets are 31-9, matching their best 40-game start (done during their 1993-94 championship season and again in 1996-97).

With some help from the Elias Sports Bureau, we can tell you that Harden became ...

• The first player with multiple games of 40 points, 15 rebounds and 10 assists in a single season since Oscar Robertson did it for the Cincinnati Royals in the 1964-65 season. He’s one of five players to have multiple 40-15-10 triple-doubles in his career, along with Wilt Chamberlain (6), Robertson (5), Kareem Abdul-Jabbar (2) and Elgin Baylor (2). Only two other players have had a single 40-15-10 game in the past 30 seasons (Vince Carter for the Nets against the Wizards in 2007 and Russell Westbrook for the Thunder against the Wizards in 2015)

• The fourth player in NBA history with back-to-back 40-point triple-doubles within a season, joining Pete Maravich (1974-75 Jazz), Michael Jordan (1988-89 Bulls) and Westbrook (2014-15 Thunder). Harden, Westbrook and Jordan are the only players to have three 40-point triple-doubles in a season during the past 30 seasons.

With a little help

As we’ve previously documented, the Rockets' bench has been a major contributor to Houston's successful run. On Tuesday, Corey Brewer had 15 points and Nene Hilario had 10. The latter finished plus-14, the highest plus-minus for any Rockets player in Tuesday's contest.

Additionally, Montrezl Harrell went 5-of-5 from the field, making him 17-of-18 (94 percent) in the past two games. Elias notes he is the first player to shoot that well while taking that many shots over a two-game stretch since Kevin Garnett went 17-of-18 over a two-game span for the Celtics in November 2009.
