The Phoenix Suns and Chris Paul have ended their respective long waits for NBA Finals appearances after a 130-103 win over the Los Angeles Clippers sealed their spot on Wednesday.

The Suns clinched the Western Conference Finals series 4-2, rounding out the triumph with an outstanding road win, with Phoenix back in the NBA Finals for the first time in 28 years.

Suns' 36-year-old point guard Paul was exceptional with 41 points as he progresses to the NBA Finals for the first time in his career, after 13 playoffs campaigns.

Paul hit seven-from-eight three-pointers in a masterful shooting display, going at 66.7 per cent from the field, as well as eight assists, four rebounds and three steals with no turnovers.

Devin Booker contributed with 22 points, four assists and seven rebounds, Deandre Ayton had 17 rebounds along with 16 points, while Jae Crowder hit five three-pointers in his 19 points.

Phoenix are crowned Western Conference champions having gone 12-4 in the postseason, including 6-2 on the road, clinching all three series away.

The Suns become the first team in history to reach the NBA Finals having not made the playoffs in 10 or more years prior.

The Clippers could not muster one more memorable comeback after some dramatic performances this postseason, closing within seven points late in the third before Paul showed irrepressible poise.

Paul George managed 21 points with nine rebounds for the Clippers, while Marcus Morris Sr scored 26 points and had nine rebounds.

Patrick Beverley was ejected in the fourth quarter for a push on Paul as reality set in for LA, who were behind for the most part of Wednesday's Game 6.

Paul's shooting was clearly on early as the Suns opened up a 10-point half-time lead, with Phoenix shooting at 58.8 per cent from beyond the arc in the first half.

The Clippers had a 10-0 run to close within seven points late in the third quarter as the home crowd erupted after Nicolas Batum's three-pointer.

But Paul steadied for Phoenix with a long-range bucket immediately after the timeout, opening it up to 14 points at the final change and they would not relent, with the Suns veteran adding 17 fourth-quarter points.

Hawks at Bucks

Star pair Trae Young and Giannis Antetokounmpo are both likely to be out for the crucial Game 5 as the Milwaukee Bucks host the Atlanta Hawks with the series at 2-2.
