The Dallas Mavericks forced a Game 5 in the Western Conference Finals after holding off the fast-finishing Golden State Warriors, winning Game 4 119-109 on Tuesday.

Luka Doncic scored a team-high 30 points for the Mavs, including a crucial fourth-quarter dunk after the Warriors closed within eight points with 3:23 to play.

The Slovenian was one assist away from a triple-double, with 14 rebounds and nine assists along with two steals and two blocks, shooting 10-of-26 from the field.

The Mavericks shot 20-of-43 three-pointers for the game to stave off elimination, with Dorian Finney-Smith contributing 23 points and Reggie Bullock adding 18 points with six triples.

Dallas, who trailed 3-0 in the series coming into Game 4, led by as much as 29 points after dominating the middle quarters before the Warriors stormed home with a 39-20 final quarter.

Golden State's bench players led the fightback, with Jonathan Kuminga scoring 17 points, but Stephen Curry was their top scorer in the game, with 20 points.

Fifteen of Curry's 20 points came in the first half, while he also had five rebounds, eight assists and one steal.

The Warriors shot 10-of-28 from beyond the arc, with Curry only managing two-of-five from three-point range, while Klay Thompson went two-of-six for his 12 points.

After the Mavs led 62-47 at half-time, the game was delayed for 16 minutes in the third quarter after heavy rain in Dallas leaked onto the American Airlines Center court from the roof.

Dallas would hold on, marking the fourth time they have won Game 4 when facing a 3-0 deficit in a playoff series, losing Game 5 on the previous three occasions.

Golden State has led 10 playoff series 3-0 in the past, sweeping six and winning in five on four occasions. 

Game 5 will take place in San Francisco on Thursday.
