Doncic fell a point short of matching Dirk Nowitzki’s team record set Nov. 3, 2009, against Utah. In just 17 minutes, Doncic was 10 for 11 from the floor, making 6 of 7 3-pointers, and hit 7 of 8 free throws.
The second-year star from Slovenia had 22 points, five assists and five rebounds in the first quarter alone. He played only 25 minutes total, but still managed 10 rebounds and 11 assists.
Doncic was coming off a 40-point triple-double Monday night against San Antonio, and has an NBA-best seven triple-doubles in 14 games this season.
The Mavericks never trailed and tied a franchise record with 22 3-pointers while sending Golden State to its worst loss since a 1973 playoff game.
The Warriors, who ended a seven-game losing streak by beating Memphis on Tuesday night, are an NBA-worst 3-13. Their five-year run of at the top of the NBA has collapsed under a weight of injuries, with Draymond Green out Wednesday because of right heel soreness.
With Green out, Golden State dressed only eight players, none of whom suited up for the team last season when it made the NBA Finals for the fifth consecutive year.
Eric Paschall led the Warriors with 22 points.
