SALT LAKE CITY -- Gordon Hayward prides himself on his self-control.
After hitting a step-back, game-winning jumper at the buzzer, he couldn't help himself. He let out all his emotion in a celebratory frenzy.
"I've never really done that before," Hayward said. "It was just one of those moments."
Hayward, who had 21 points, broke free of James to catch an inbounds pass, faked a move to the basket and then stepped back on the right wing and swished a 21-foot jump shot as the horn sounded.
The forward was mobbed by his Jazz teammates in a scene reminiscent of a college tournament game.
"How can you not show emotion after a finish like that? For us to win the game after being in control the whole game and then see it slipping away, it was pretty special," Hayward said. "Just exhilaration!"
Derrick Favors had 21 points and 10 rebounds but the Jazz had to overcome a last-minute effort by James, who scored 31 points as Cleveland fell to 1-3.
With the Cavs down four points with 17 seconds remaining, James made a 3-pointer from the corner off a deflected pass while falling away out of bounds. He then made all three free throws after faking Favors into a foul on a 3-point attempt to tie the game at 100 with 3.4 seconds left.
The Jazz led the entire way -- by as many as 16 points -- until the fourth quarter, when Irving scored 10 points in a 14-6 run that gave the Cavaliers an 89-86 edge with 4:43 remaining.
The Jazz went back in front and led 93-89 when Trevor Booker beat the shot clock with a 3-pointer. The next play down, Booker was whistled for a flagrant-1 foul on Love. The two exchanged words and each got a technical, ratcheting up the intensity in the already tight contest.
The Cavs allowed the Jazz to shoot 51 percent in their second of three games in the West. After losing the previous night 101-82 to Portland, Cleveland made it much closer but couldn't overcome Hayward's heroics.
"Rome wasn't built in a day and we understand that," James said. "You have to continue to work the process. You hate to lose as competitors, but we felt like tonight we improved. We improved and proved in the second half we're capable of playing some good basketball."
Enes Kanter had 18 points for the Jazz.
"It is a really big win for our team. For this team (Cleveland), you just get pumped up," Kanter said.

DOING IT HIS WAY
Hayward told Utah coach Quin Snyder he wanted to take the final shot. Synder instructed him to make sure he drove it to the basket. "I may have disobeyed what he said . I started to drive but I just read the defense and saw the step-back was open," said Hayward, who posted only his second career game-winning shot.
Irving dazzled the crowd and confounded his defenders with a variety of spinning forays to the hoop. More than half his baskets came on drives -- layups, hooks and floaters from either hand. Only problem was that the point guard didn't record a single assist.
