Phoenix Suns veteran Chris Paul is refusing to talk about a drought-breaking NBA Finals appearance despite his side taking a 3-1 lead in their Western Conference finals on Saturday.

The Suns won 84-80 over the Los Angeles Clippers to move within one victory of the franchise's first Finals appearance since 1993.

Paul, 36, debuted in the NBA in 2005 and is an 11-time All Star yet has never played in an NBA Finals series either.

"Not til the job is done. We can talk about all that then but right now it's laser focus," Paul said during the post-game news conference.

"Three wins don’t win a series. We did what we came to do. We got one of these [road wins]. We've got to stay focused. We need one more [win]."

Paul has played in 12 NBA playoffs series, coming closest to the NBA Finals in 2017-18 Conference finals with the Houston Rockets having been 3-2 up.

When asked about previously falling short, Paul added: "Everything happens for a reason. Don't dwell on things. I'm here now, excited about this opportunity. All I can worry about right now is Game 5."

Paul finished with 18 points but hit several last-quarter free-throws to ice the game after Devin Booker fouled out.

"It was crazy when I went to the free-throw line, I thought about my son," he said. "I talk to my son all the time about the importance of shooting free-throws. He's really getting into basketball.

"I seriously went to the free-throw line, I thought 'how the hell am I going to tell him to stay poised, if I don't'."

Paul, who missed both Game 1 and 2 after entering into the NBA's health and safety protocol, said he was excited to play at home for the first time in the series on Monday.

"I didn’t get a chance to feel that energy in Game 1 and 2," he said. "I was at the crib with my family. I'm excited to go back to Phoenix."
