Brent Barry may have felt he was fouled, but he refused to admit a no-call on his last shot helped the Los Angeles Lakers hold off the San Antonio Spurs 93-91 in Game 4 of the Western Conference final at the AT&T Center on Tuesday night.

Trailing 93-91 with 2.1 seconds remaining, Spurs forward Robert Horry in-bounded to Barry, who was bodied by a leaping Derek Fisher as he put the ball on the floor.

"That is not going to get called in the Western Conference finals," Barry said. "Maybe in the regular season."

"I think we met simultaneously, and there was contact for sure," Fisher said. "But I don't think I ran through him."

Barry threw up a shot from well beyond the arc that hit the backboard as time expired, and he threw up his arms in disgust as no foul was called on the play.

"If I was the official, I would not have called that a foul," Spurs head coach Gregg Popovich said.

"No foul, no foul," said Lakers guard Kobe Bryant, who poured in 28 points and pulled down 10 rebounds.

Lamar Odom scored eight of his 16 points in the fourth quarter for the top-ranked Lakers, who lead the best-of-seven series 3-1.

Vladimir Radmanovic provided 11 points, while Pao Gasol had 10 points and 10 rebounds.

"Their energy was terrific," Lakers head coach Phil Jackson said. "Coming out and responding to a loss and getting a lead ... and playing with that kind of energy, I think, carried us over."

Game 5 goes Thursday at the Staples Center, where the hometown Lakers remain unbeaten in the playoffs (7-0).

"It is very important that we play a similar type of game that we played tonight, with the kind of energy that we had," Jackson said.

"It is one loss and elimination," Spurs forward Tim Duncan said. "But we really feel, if we clean a lot of this stuff up, we have an opportunity to get right back in this series."

Duncan led all players with 29 points and 17 rebounds for the third-seeded Spurs, who, last season, won their fourth NBA championship in the past nine years.

Barry and Tony Parker both scored 23 points.

"We missed a lot of easy shots," Parker said. "You know, myself, Timmy, we missed a lot of layups.

"It was just never … we never got in a good rhythm."

'We responded every time'

Los Angeles stormed out to a 22-8 lead, but San Antonio went 17-of-17 from the free-throw line to trim the deficit to 53-46 at halftime.

The Spurs stayed within striking distance and tied it 65-65 on Parker's basket with 4 1/2 minutes left in the third quarter.

The Lakers swiftly regained the lead and took a 77-70 advantage into the fourth, and stayed in front because the Spurs missed 10 of 11 shots before Barry hit a three-pointer to make it 77-75 with 10 minutes to go.

After teams swapped four points apiece, the Lakers tallied seven consecutive points to take a 88-79 lead.

"We responded every time that they came in and tied the ball game," Jackson said.

Manu Ginobili's three-pointer sliced it to 93-89 with 50 seconds left. After Bryant missed on a challenging layup in the final minute, Parker was knocked into the seats on a driving layup by Odom, who was called for goaltending.

That made it 93-91 with 28.1 seconds left, but the Spurs failed to regain possession as Fisher's airball struck Horry's leg and bounced out of bounds.

Bryant then hit the rim on a catch-and-shoot, leading to Barry's missed three-point attempt with 2.1 seconds remaining.

"Game 3 was an opportunity for us to learn in terms of how hard we need to play, the speed we need to play with," Bryant said. "Tonight we came out and did a much better job to win in this building."

Los Angeles has prevailed in seven of 11 playoff series with San Antonio, including the 2001 conference final.
