PHOENIX - With his team in a deep hole, Jerry Sloan turned to his bench. The result was a big rally and a tough road win for the Utah Jazz. Carlos Boozer dunked with 31 seconds left for the go-ahead score and the Jazz finished the game on a 13-3 run to beat the Phoenix Suns 108-104 on Friday night.

But the Jazz never would have been in position to win had it not been for reserves Matt Harpring, Derek Fisher and Gordan Giricek ¡ª inserted by Sloan with his team down by 15 points in the third quarter. It was a luxury the depth-shy Jazz of a year ago could not have afforded.

"I'm going to tell you what happened. The bench came in and gave us a big boost," Boozer said. "It gave us energy and they're the ones that got us back in the game."

Boozer had 21 points and 12 rebounds for the Jazz, who trailed 101-95 after Leandro Barbosa's two free throws with 2:26 to play.

Phoenix still led 103-101 on Steve Nash's two free throws with 1:10 left. But Harpring was fouled by James Jones on a layup and made the three-point play to put Utah ahead 104-103 with 57 seconds remaining.

Kurt Thomas made one free throws with 44 seconds left to tie it at 104.

Boozer broke free after a tussle with Thomas for the ball to get the go-ahead stuff. Barbosa missed an open baseline layup that would have tied it.

"I don't know what happened," Barbosa said. "I thought the ball was going to go in. I think I gave the ball too much spin on the backboard. Nobody likes this ball. It's OK. We've got to keep it up. We have another game tomorrow, but it was a tough one."

Fisher's two free throws with 9.3 seconds left sealed the victory.

"They're a tough team to guard but we did our best," Harpring said, "and we took advantage of some mismatches that they gave us."

It was the second time in their three games that the Suns failed to hold on to a big lead.

"We're just not quite in synch," Suns coach Mike D'Antoni said. "We have a couple of guys that are out of synch. I've got to get them back in there and get them playing. The bright spot is that in all the games we've been in we're up by 19, 15 ¡ª we just can't hold it."

Barbosa, inserted into the starting lineup in place of Boris Diaw, scored 22 points, nine in the final 5 1/2 minutes, but was just 5-for-15 from the field. Shawn Marion had 19 points and Nash added 17 points and 10 assists. Raja Bell scored 17 points before fouling out with 4:37 remaining.
