Steve Nash, who joined the Mavericks during Nowitzki's rookie season in 1998-99 and played with him in Dallas until 2004, congratulated the 13-time All-Star on Instagram.
Nowitzki became the sixth player to surpass the 30,000-point mark in National Basketball Association history - joining Kareem Abdul-Jabbar, Karl Malone, Kobe Bryant, Michael Jordan and Wilt Chamberlain in the elite group.
Nowitzki reached the mark after nailing a step-back baseline jumper over Lakers reserve forward Larry Nance Jr. for a 42-30 lead with 10:57 left in the second quarter.
DIRK Nowitzki came out firing, nabbing the 30,000-point mark in over a quarter, as the surging Dallas Mavericks asserted their mastery over the hapless Los Angeles Lakers with another romp, 122-111, at the American Airlines Center on Tuesday (Wednesday, Manila time).
National Basketball Association commissioner Adam Silver paid tribute to Nowitski's achievement in a statement, hailing the Mavs star as "a model player and terrific ambassador for our game".
"Throughout his 19 seasons with the Mavericks, Dirk has been a model player and terrific ambassador for our game", NBA Commissioner Adam Silver said in a statement issued in honor of Tuesday's achievement.
Eric Bledsoe had a game-high 30 points for the Suns in the loss.
After the signature shot for 30,000, Nowitzki added a 3-pointer for 23 points in the first 14 minutes before the game was stopped as teammates mobbed the wide-smiling star near midcourt.
"It says that Dirk is obviously a great player".
"Twenty is a great number", Nowitzki said last week in an interview. The Lakers dropped to 19-45. And he says it's a credit to Nowitzki's ability to play into his late 30s. So I kind of want to make the 20 fold. I think that's also a good number to be in the league ... from 20 to 40.
