Hayward scored 24 points to help the Jazz beat the Los Angeles Lakers 96-88.
The Jazz ended a two-game losing streak and the Lakers have now dropped eight of their last nine.
"It sounds nice," Hayward said about being an All-Star. "Definitely just rewarding for a lot of work that I did. Definitely wouldn't have gotten it without my teammates, without the coaches. Put in a lot of work in this summer with Johnnie Bryant and Isaiah Wright.
"We've been a lot more successful this year than in past years. I've always said, when a team's successful the individual accolades come after that."
Utah used a 16-0 run in the third quarter, punctuated by a Joe Ingles-to-Hayward alley-oop to give the Jazz a 68-56 lead that they never relinquished. The stretch was jump-started by Rudy Gobert's rim protection on the defensive end as the Lakers went more than six minutes without scoring. He finished with six blocks, matching his season-high.
The Lakers answered with a 14-4 fourth-quarter run, but never got closer than 80-76.
"I don't think we're playing real well right now," Jazz coach Quin Snyder said. "It's not surprising given the amount of games we've played recently and re-integrating certain players -- every week there's a new guy that's able to play. What that does is, it affects your rhythm.
"The beginning of the third quarter Rudy took the game over on the defensive end. That's how we're going to win."
Hayward had another efficient night, shooting 7 for 14 from the field while George Hill chipped in 12.
The short-handed Lakers struggled to find offense against the best scoring defense in the league were just 4 for 14 from 3-point range. Lou Williams scored a team-high 20 off the bench while both Jordan Clarkson and Ivica Zubac added 16.
"We went dry," Lakers forward Larry Nance Jr. said. "Couldn't hit the broadside of a barn. Our offense just wasn't clicking for us tonight."

Hayward was named a reserve on the Western Conference All-Star team Thursday, his first time making the team. The seven-year veteran is the first Jazz player to reach the All-Star team since Deron Williams in 2010-11. He entered Thursday averaging a career-high 21.8 points and 5.7 rebounds to go along with 3.5 assists and 1.0 steals.
OUTSIDE LOOKING IN
Gobert did not make the All-Star team. The 7-foot-1 Frenchman leads the league in blocks (118), defensive rating (97.8), true shooting percentage (.682) and points per shot (1.88) and is second in field goal percentage (.664) and offensive rebounds (176) and third in total rebounds (591).
"I'm frustrated, but it's not what I play for," Gobert said. "I play to win games. I try to keep improving every day. You know, that's how it is. There's some things you can't control sometimes and I make sure I control what I can control.
"I thought I had a chance, but I already knew how it works in this league. I thought I had a chance, but I wasn't counting on it."
Gobert smirked when asked if it's motivation for the future and said, "That's a dumb question."
"For whatever reason, in the second half we kept trying to challenge him," Lakers coach Luke Walton said about Gobert. "He's probably the best shot blocker in the league and he showed us why tonight."
