CLEVELAND -- Rookie Luka Doncic matched his season high with 35 points and did a little bit of everything for Dallas, and Harrison Barnes scored 13 in the fourth quarter to lead the undermanned Mavericks to a 111-98 victory over the Cleveland Cavaliers on Saturday night.
With a contingent of fans waving Slovenian flags to support Doncic, the 19-year-old showed why the Mavericks are so excited about their future. He added 11 rebounds, six assists and made a couple long 3-pointers that drew gasps from the Quicken Loans crowd.
Barnes made three 3-pointers in the fourth and finished with 17 points, and rookie Jalen Brunson added 15 for the Mavericks, who played their second game since acquiring star Kristaps Porzingis from New York in a blockbuster trade. Tim Hardaway Jr., Courtney Lee and Trey Burke also came in the deal but are not eligible to play until their physicals are completed.
Jordan Clarkson scored 19 for Cleveland.
The Cavaliers, who have been dealing with injuries all season, suffered another one as forward Cedi Osman went out in the first half with a right ankle injury and did not return.
Due to the trade, Dallas coach Rick Carlisle had only nine dressed players.
Fortunately, one of them was Doncic, who sat out Thursday's game in Detroit with a sore left ankle.
Doncic scored 18 points in the first quarter, when he became the sixth player since 2000 to score 1,000 points before turning 20. LeBron James, Kevin Durant, Carmelo Anthony, Devin Booker and Dwight Howard did it before Doncic, who will be 20 on Feb. 28.
Doncic finished the first half with 28 points, 10 in the final 3:56 after the Mavericks went more than six minutes without a field goal.
However, it was Brunson and Barnes who had the bigger impact in the second half. Shortly after replacing Doncic, Brunson converted a 4-point play with 8:56 left and Barnes made his 3s, the last giving Dallas a 106-91 lead with 4:34 left.
