Auburn Hills, Mich ? Big Shot Bob did it again.

Robert Horry, the veteran player whose clutch postseason three-pointers have defined his career, knocked down a wide-open three with 5.8 seconds remaining in overtime Sunday night to give the San Antonio Spurs a 96-95 victory over the Detroit Pistons in Game 5 of the NBA Finals.

The Spurs took a 3-2 lead in the best-of-seven series, bouncing back from a pair of lopsided losses to defeat the defending champs in their own building and send the series back to San Antonio needing just one more victory for their third title in seven years.

Horry inbounded from the left sideline near midcourt with 9.4 seconds left, finding Manu Ginobili in the corner. Detroit’s defenders collapsed on Ginobili and left Horry wide open for the return pass.

Bad idea, as so many of Horry’s opponents have learned in the past.

“Manu cut to the basket and Rasheed bit,” Horry said. “I’ve been shooting it pretty good so I just let it fly.”

Detroit had one final chance after Horry’s shot, but Richard Hamilton missed a runner from the lane, and Bruce Bowen rebounded to end it, allowing the Spurs to run off jubilant.

After four blowouts, this was the type of game everyone had been waiting almost two weeks to see – an intense, closely fought nail-biter befitting of a championship series. The fourth quarter was close throughout, with clutch shots coming from Chauncey Billups and Hamilton for the Pistons, and Horry and Ginobili of San Antonio.

The player who wasn’t hitting the big ones was two-time NBA Finals MVP Tim Duncan, who missed six straight foul shots and a putback at the end of the fourth quarter that would have won it for the Spurs.

Duncan also missed San Antonio’s first two shots of overtime and lost control of an entry pass with 56 seconds left in the extra period with Detroit ahead 95-93.

An offensive rebound gave Detroit two possessions while running down the final minute of overtime, but Billups missed on a drive with 9.4 seconds remaining. After a timeout, Horry knocked down the three that won it.

Asked what the difference was in this particular game, a relieved looking Duncan turned to Horry and said: “Big-shot Bob.”

Horry, trying to join John Salley as the only players in NBA history to win championships with three different teams, has reached the playoffs in all 13 of his NBA seasons and has built a reputation for knocking down huge three-pointers.

But the late three wasn’t the only big shot by Horry, whose offensive poise was a direct contrast to Duncan’s troubles.

The Pistons were ahead 87-85 before Horry caught a pass and quickly launched a three-pointer that dropped through with 1:17 left in regulation, giving him seven straight points for the Spurs. Duncan had a chance to extend the lead after Hamilton missed a jumper, but the career 69 percent foul shooter missed a pair from the line with one minute remaining.

Billups scored on another of his crafty drives to give Detroit an 89-88 lead, and the Pistons fouled Duncan when he got the ball down low on the next possession. With the crowd noise at its loudest of the series, Duncan missed the first foul shot – making him 0-for-6 in the period – but made the second.

San Antonio’s best defender, forward Bruce Bowen, took over the defense against Billups on the next possession, and there appeared to be contact as Billups drove the lane and missed. But no foul was called, and San Antonio got the ball back with 16.9 seconds left able to hold for the last shot.

Ginobili dribbled the clock down and drove on Tayshaun Prince, but missed the shot. Duncan was there for the rebound, grabbed the ball with two hands and had a wide-open chance for an easy putback, but his shot somehow came up short – and Duncan walked off with his hands balled into fists covering his mouth as the game was sent to overtime.

Game 6 will be Tuesday night, and Game 7, if necessary, on Thursday.

“We view this game 6 as the one we’ve got to get,” Duncan said. “These guys are great in Game 7.”

The Pistons haven’t won in San Antonio since 1997, and the Spurs had the NBA’s best regular-season home record.

Horry finished with 21 points, Duncan had 26 points and 19 rebounds, Manu Ginobili scored 15 and Tony Parker 14.

Billups led Detroit with 34 points.

Of the prior 23 times a finals series has been tied 2-2, the Game 5 winner has gone on to win the title 17 times. The most recent time it has happened was 2003, when San Antonio defeated New Jersey. The most recent time the Game 5 loser has won following a 2-all tie came in 1994, when the Houston Rockets defeated the New York Knicks in Games 6 and 7.

The Spurs were much more aggressive in terms of taking the ball to the basket – the one things they had done best in the first two games – and Ginobili was especially effective in the early going.

One of the prettiest ball movement sequences came early in the second quarter, the ball changing hands five or six times before Ginobili fired a hard pass to his left for a wide-open 3-pointer by Bruce Bowen that put San Antonio ahead 27-24.

San Antonio gradually built its lead to 38-29 before Detroit closed the half with a 13-4 run for a 42-42 tie.

Billups had a pair of airballs early in the third quarter, one of which hit the supports behind the backboard, but he came back with a long jumper and a three-point play in transition for a personal 6-0 run that tied it at 61-all before Horry ended the quarter with a 3-pointer – a preview of what was to come.

Notes: Coach Gregg Popovich Popovich removed backup point guard Beno Udrih from the rotation, using Brent Barry and Devin Brown in that role during the brief stretches when he rested Parker. Udrih had been having trouble against the pressure defense of Lindsey Hunter. … Officials Ron Garretson, Steve Javie and Mike Callahan worked Game 5. The Pistons are 0-5 in the playoffs with Garretson on the court. … Recording star Kid Rock sang “America the Beautiful” a capella while wearing a vintage Rick Mahorn warmup jersey. He closed the song with a shout of “Let’s rock!” before putting his black hat back on and giving a satisfied nod to the crowd, which ate it up.
