Dallas Mavericks All-Star Luka Doncic hasn't even finished his second season in the NBA, but he has already tied Jason Kidd for the most triple-doubles in Mavs history.

With a 26-point, 14-assist, 10-rebound performance on Wednesday against the San Antonio Spurs, the second-year superstar matched Kidd's record of 21 career triple-doubles.

The Slovenian star now also has 14 more triple-doubles before his 21st birthday than any other player in league history. Magic Johnson and LeBron James have seven and five triple-doubles in their careers, respectively, before turning 21.

After putting out one of the best rookie seasons in recent memory, Luka Doncic has undoubtedly taken his game to a whole new level in season number two. The former No. 3 overall pick is averaging 28.8 points, 9.5 rebounds and 8.6 assists per game while shooting 46.5 percent from the field and 32.4 percent from beyond the arc.

Doncic's evolution into an MVP-caliber superstar also has the Mavs currently set to make the playoffs for the first time since the 2015-16 season. Dallas is currently the seventh seed in the Western Conference with a 36-23 record.

As for Jason Kidd,  the Hall of Fame point guard spent eight seasons in Dallas where he averaged 10.5 points, 8.4 assists and 5.5 rebounds per game while also winning a championship with the team in 2011.
