DALLAS (AP) — All Devin Booker can do now is wait for the announcement of All-Star reserves.

The last impression for the Phoenix guard was a good one.

Booker scored 20 of his 32 points in a decisive third quarter, Deandre Ayton had a season-high 31 points and the Suns never trailed in a 133-104 dismantling of the Dallas Mavericks on Tuesday night.

Eighth in the NBA in scoring, Booker is tied for fourth with Portland’s Damian Lillard with 20 games of at least 30 points. They trail three All-Star starters in James Harden, Giannis Antetokounmpo and Trae Young. The reserves will be announced Thursday.

“It’s exciting just to be in this situation,” said Booker, who was 7 of 9 from the field in the third and 12 of 20 for the game. “Every time I go out on the floor, I try to represent Phoenix, represent my last name in the best way possible and I think making All-Star would amplify that and give something that this city’s been waiting on for a long time.”

Booker started the scoring in the third quarter before the ball had even been thrown in, making a free throw after the last of three first-half technicals against Dallas was called against Tim Hardaway Jr. after the halftime buzzer.

With the head start from Booker, the Suns outscored the Mavericks 48-22 in the third on their way to surpassing last season’s win total of 19 with their fourth victory in the past five road games.

It was the most points in a quarter for Phoenix since 1990, and the most the playoff-contending Mavericks have given up in any quarter in franchise history.

“This team has done so many things to get people excited about it and really worked hard to get into a solid position at this point in time,” coach Rick Carlisle said. “A performance like this is just tough. Nights like this do happen, but this was extreme.”

Ayton, the 2018 No. 1 overall pick who has been overshadowed during his two seasons by Dallas sensation and third overall choice Luka Doncic, was 13 of 15 from the field as the Suns shot a season-high 59%. Ayton made all five of his free throws and had a game-high nine rebounds.

Doncic, an All-Star starter, scored 21 points with six rebounds and just two assists before leaving the game for good with the Mavericks trailing by 36 with 8:05 remaining. He was the only starter in double figures for Dallas, which was just 7 of 33 from 3-point range.

Doncic and Carlisle drew techs in the first quarter before Hardaway was called for one on his way off the floor not long after he was called for an offensive foul that Carlisle unsuccessfully challenged.

Booker’s free throw started an 8-0 run to open the second half and give Phoenix a double-digit lead for good after Dallas had trimmed a 13-point deficit in the first half to five (60-55) at the break.

Now the Suns go home for the first time since the shocking death of former Los Angeles Lakers star Kobe Bryant in a helicopter crash Sunday.

“It’s been hard and it will be hard going forward, but I was just proud of the way our guys made plays for each other,” coach Monty Williams said. “I don’t think anybody expected us to come in here and win the game.”

KOBE TRIBUTES

The Mavericks honored Bryant in a ceremony before their first home game since the crash that also killed his 13-year-old daughter Gianna and seven others outside Los Angeles.

Highlights of Bryant’s career and some of his interactions with the Mavericks, including retired star Dirk Nowitzki, were shown on the video boards during a moment of silence. Nowitzki was courtside with owner Mark Cuban.

Dallas’ plan to retire the No. 24 in Bryant’s honor was announced to cheers, and the teams repeated the tribute Dallas and Oklahoma City displayed a night earlier. The Mavericks took an 8-second backcourt violation to honor Bryant’s other number, followed by a 24-second shot clock violation by the Suns.
