THE DALLAS Mavericks have an opportunity to reach the NBA Finals for just the third time in franchise history when they seek to close out a sweep of the visiting Minnesota Timberwolves in Game 4 of the Western Conference finals Tuesday night.

The Mavericks scored 14 of the final 17 points for a 116-107 home win in Game 3 on Sunday night that left them five wins away from their second-ever NBA title, having captured the crown in their last visit to basketball’s grand stage in 2011.

Luka Doncic and Kyrie Irving scored 33 points each Sunday, but the Mavericks also got key contributions from P.J. Washington, Daniel Gafford and Derrick Jones Jr. in a win that gave them a 3-0 series lead.

Gafford, acquired in February from the Washington Wizards, had to put in yeoman’s work after big-man sidekick Dereck Lively II departed with a sprained neck in the third quarter.

Gafford wound up playing a playoff career-high 29 minutes and saved his best for last, blocking a Mike Conley layup attempt with 56 seconds left before slamming down Doncic’s alley-oop pass 22 seconds later to clinch the win.

Lively went straight to the locker room after catching Karl-Anthony Towns’ knee to the back of his head while falling in pursuit of a rebound. He reportedly passed a concussion test, but his status for Game 4 remains uncertain. He was listed as doubtful on the Mavericks’ injury report Monday afternoon.

The Mavericks had better news with forward Maxi Kleber upgraded to questionable for Game 4. Kleber has not played since May 3 because of an AC joint shoulder separation.

With or without Lively, Gafford acknowledged after Sunday’s win that the Mavericks’ success inside is tied to the unselfish play of Doncic and Irving.

“We’re trying to find the seams and just what can put us in position to where we can help the team,” Gafford said. “Everybody just put trust in us to just finish around the basket. And that’s what we did.”

The last time the Mavericks had a 3-0 lead in a playoff series was in 2011 when they finished off the sweep of the Los Angeles Lakers in the West semifinals en route to the title. — Reuters
