Luguentz Dort scored 14 of his 30 points in overtime to lift the Oklahoma City Thunder to a 120-114 win over the host Dallas Mavericks.

Rookie Tre Mann added a season-high 29 points for the Thunder, who have won back-to-back games for the first time since late December.

Dort took over in the extra period, scoring 14 consecutive Oklahoma City points to help the Thunder overcome a big night by Luka Doncic.

After the teams traded baskets to start overtime, Dort answered a Mavericks bucket with a 3-pointer to give Oklahoma City the lead for the final time.

He hit another 3-pointer with 30 seconds left to stretch the Thunder's lead to seven points and all but put the game away.

The Thunder led for much of the fourth until Reggie Bullock's corner 3-pointer with less than 10 seconds left put the Mavericks up by two.

But Josh Giddey hit a streaking Kenrich Williams at the bucket on the inbounds pass to tie it up.

Doncic missed a long 3-pointer at the buzzer to send the game to overtime.

The game stayed tight throughout much of the night, with neither team leading by more than eight until the Thunder went on a 15-4 run -- hitting three 3-pointers -- late in the third to take an 11-point lead in the final minute of the quarter.

Mann, who hadn't scored more than 19 before Wednesday's game, hit six 3-pointers.
