A 13-point first-quarter lead became a 26-point advantage by half-time, and the result was as good as sealed midway through the third when Dallas pulled away by 38.

Luka Doncic top-scored for the Mavericks with 29 points, while Tim Hardaway Jr added 15 off the bench.

Meanwhile, Jayson Tatum’s 15 points led the way for Boston, who shot just 36 per cent from the floor.

The series returns to Boston for game five on Monday, with the Mavericks aiming to become the first team in NBA history to win a series after giving up a three-game lead.
