Kawhi Leonard matched his playoffs career high with 45 points to keep the Los Angeles Clippers' NBA season alive with a 104-97 victory at the Dallas Mavericks.

The fourth-seeded Clippers were facing elimination on Friday, trailing Luka Doncic's Mavericks 3-2 in the Western Conference first-round series.

But Leonard came up big for the Clippers with their backs against the wall, erupting on 18-for-25 shooting and five three-pointers to level the series and force a deciding Game 7.

Leonard made only seven of 19 shots in Game 5, after going 38-for-53 (71.7 per cent) over his previous three games, however, the NBA champion was far more efficient in Game 6 as attention now turns to Sunday's decider in Los Angeles.

For the first time in their history, the Clippers won three road games in one series, with Paul George contributing a double-double of 20 points and 13 rebounds as Reggie Jackson put up 25 points.

Luka Doncic – carrying 361 points from 11 playoff games into the contest, the highest total at that point of his career since Hall of Famer Michael Jordan (405) in 1988 – posted 29 points but he was just two-of-nine shooting from three-point range, while team-mate Tim Hardaway Jr. added 23 points.

The Mavericks were 17-10 (63.0 per cent) in potential series-clinching games prior to tip-off – the third best record in NBA history (minimum 10 games), behind only the Golden State Warriors (42-23, 64.6 per cent) and Cleveland Cavaliers (25-14, 64.1 per cent), according to Stats Perform.

They made a strong start by outscoring the Clippers 28-26 in the opening quarter, though Leonard and the visitors wrestled back momentum in the second period for a 48-45 half-time advantage.

The see-sawing contest continued as the Mavericks used a 32-25 third quarter to close in on a potential Conference semi-final against the top-seeded Utah Jazz.

However, Leonard flexed his muscles in a dominant final period to avoid joining city rivals and champions the Los Angeles Lakers in exiting the postseason.
