SALT LAKE CITY — The Utah Jazz had plenty of chances to crumble and nearly did.

They let a 12-point lead slip away in the last four minutes and faced overtime against league MVP Kobe Bryant and the Los Angeles Lakers. Instead of wilting, Utah played its toughest defense of the playoffs and pulled out a 123-115 victory yesterday, tying the Western Conference semifinals 2-2.

The Jazz held the Lakers to two field goals in overtime and went 9 for 9 from the foul line while outscoring the Lakers 15-7.

"We never have any doubts in our confidence," said Utah's Andrei Kirilenko, who blocked Bryant twice in overtime and converted a three-point play with 35 seconds remaining to help the Jazz pull away.

After opening the series with two losses in Los Angeles, the Jazz came home and answered with two wins to make it a best-of-three series, starting Wednesday at the Staples Center. Game 6 will be Friday back in Salt Lake City, where the Jazz are 4-1 in the playoffs.

Deron Williams had 29 points and 14 assists, and Carlos Boozer scored 12 of his 14 points in the second half and grabbed 12 rebounds for Utah. Mehmet Okur added 18 points and 11 rebounds, and Kirilenko finished with 15 points and five blocks.

Bryant, who said he was fighting back spasms from early in the first quarter, finished with 33 points and 10 assists.

"No excuses for me. (Kirilenko) did a great job," Bryant said. "They did a terrific job. They got big plays when they needed to."

And Los Angeles helped by sending the Jazz to the foul line 20 more times than the Lakers, who made it worse by missing 11 of 25 foul shots.

Lamar Odom added 26 points and 13 rebounds, and Pau Gasol scored 23 and pulled down 10 boards for the Lakers. Derek Fisher finished with 15 points, scoring 10 straight as the Lakers rallied in the fourth, but had no assists and got in early foul trouble.

Lakers coach Phil Jackson said his team was depending too much on Bryant.

"I still thought he went to the basket hard at the end," Jackson said. "He was still able to get to the basket and do what he wanted to do. He was out there to make plays."

Utah sank 40 of 76 (53 percent) shots and had a huge advantage at the foul line, making 37 of 45. The Jazz reserves also dominated the Lakers', outscoring them 39-16.

"Our bench stepped up and provided us with a lot of scoring and a lot of energy. We need to take that to L.A.," Williams said. "We're confident now but we still need to prove we can win on the road."

Williams had a chance to win it at the end of regulation but was blocked by Fisher, his teammate a year ago. But the Lakers' momentum stopped there as the Jazz regained their composure.

"Everybody here's been in overtime games. It's just another five minutes added to the clock," Williams said.

The Lakers struggled in the extra period and didn't score until a layup by Bryant with 1:10 remaining cut Utah's lead to 112-110. Los Angeles almost forced the Jazz into a shot clock violation before Kyle Korver got off a shot from the corner just in time. The ball bounced off the rim right to Okur, who passed it back outside to Williams, and Utah was able to burn some time before Williams slipped a pass to Kirilenko, who dunked it while getting fouled by Lamar Odom.

Kirilenko made the free throw to put Utah up by five and the Jazz hit the rest of their free throws to clinch it.

Utah backup guard Ronnie Price also had a big game, despite finishing with four points and two assists. Price had to get four stitches for a cut over his right eye after he was flagrantly fouled in the second quarter by Ronny Turiaf, who was ejected.

Price came back in the second half with one of the plays of the game.

Luke Walton had a clear path for a layup or dunk after a missed 3-pointer by Price, who caught him from behind and blocked the shot midway through the fourth to keep Utah's lead at 92-84.

"That was the play of the game," Boozer said.
