Luka Doncic said Dallas Mavericks team-mates always "had my back" after the guard delivered a match-winning performance in Game 5 against the Utah Jazz.

The Texan outfit moved to 3-2 in their first-round playoff at the American Airlines Arena with a 102-77 rout, posting the biggest blowout scoreline of the series to date.

Two days on from posting an impressive double-double in a nail-biter in Salt Lake City, Doncic was at the heart of victory for the Mavericks, with 33 points, 13 rebounds and five assists.

But the flashpoint of a hard foul from Hassan Whiteside late on in the fourth quarter perhaps exemplified the hosts' unity, as players rushed in to protect 23-year-old Doncic.

Dorian Finney-Smith and Reggie Bullock exchanged pushes with the former after he had deposited Doncic on the court, and the Slovenian admitted their response was "what great teams do".

"They had my back," Doncic said after the match "Both of them, anybody, we had each other's back. That's what great teams do. I would go with these guys to war. This is a special team."

Doncic's haul also saw him become only the second man to hit a triple mark across his first 15 career playoff games, after taking his tally to 499 points, 137 rebounds, and 133 assists.

He and Oscar Robertson are the only players in NBA history to reach 450+ points, 125+ rebounds, and 125+ assists through their first 15 career playoff games, the league said.

It has marked an impressive return after missing the first three games through a calf injury, and Doncic admits he felt more comfortable in victory the second time around.

"The first game, I was a little janky – I use this word a lot," he said. "But I felt better today.

"I think the run in the third I was a little tired, too, but just getting my air back. I've got to hydrate for Utah now, the altitude."

The Mavericks travel back to Salt Lake City on Thursday, looking to wrap up a series win in Game 6, with a final clash back in Dallas pencilled for Saturday if the Jazz force them all the way.
