Devin Booker was the most notable omission as six first-timers won NBA All-Star selection among the 14 reserves named on Thursday.

Jimmy Butler, Chris Paul and Russell Westbrook headlined the list of players selected by NBA coaches to round out the roster options for Team LeBron and Team Giannis.

Phoenix Suns guard Booker was denied a place despite averaging 27.1 points, 4.1 rebounds and 6.4 assists through 44 games this season.

Oklahoma City Thunder veteran Paul, Houston Rockets star Westbrook, Damian Lillard of the Portland Trail Blazers and Utah Jazz youngster Donovan Mitchell snatched Western Conference guard spots, the latter handed his maiden selection alongside team-mate and fellow first-timer Rudy Gobert.

Brandon Ingram, Bam Adebayo, Jayson Tatum and Domantas Sabonis will also be among the newcomers at United Center in Chicago on February 16.

Suns general manager and three-time NBA champion James Jones questioned Booker's absence.

"I've played with and against multiple All-Stars in this league and Devin Booker is undoubtedly an NBA All-Star," Jones said in a statement.

Frenchman Gobert's inclusion alongside Sabonis (Lithuania), Ben Simmons (Australia) and Nikola Jokic (Serbia) plus starters Luka Doncic (Slovenia), Joel Embiid (Cameroon), Pascal Siakam (Cameroon) and Giannis Antetokounmpo (Greece) lifts the number of international players to eight, a record for an All-Star Game.

The 2020 edition will feature several format changes to honour Kobe Bryant after the Los Angeles Lakers legend, his 13-year-old daughter Gianna and seven others died in a helicopter crash on Sunday.

Among them will be a 'target score' to chase in a timeless fourth quarter, the figure being the leading team's tally after three periods plus 24 points - representing the number Bryant wore during the second half of his glittering NBA career.

LeBron James and Milwaukee Bucks forward Antetokounmpo, the designated captains, will select their teams from the available player pool on February 6.
