SEATTLE (Ticker) -- Tim Duncan and David Robinson were big down the stretch - literally.
Duncan and Robinson used their size to help open a 10-point lead in the final two minutes and the San Antonio Spurs held on for a 91-88 victory over the smallish Seattle SuperSonics.
Duncan finished with 18 points, 15 rebounds and four blocks and fellow 7-footer Robinson added 18, 10 and three as they overpowered the SuperSonics, who rank near the bottom of the NBA in rebounding and blocked shots.
"They were forcing their way in," Seattle guard Brent Barry said. "I don't know how many shots Tim made from the field other than tipping the ball in. It seemed like he didn't make anything in the turnaround mode or shoot that sweet shot off the backboard. He just had his fingertips up around the tin all night long and kept putting balls back."
"All throughout the season, not being able to keep teams off the boards," lamented SuperSonics coach Nate McMillan. "Tonight, that was huge."
Duncan had a tip-in and an inside bucket around a free throw by Seattle's Gary Payton to give San Antonio an 84-81 lead with 3:59 to go. After a jumper by Tony Parker, Robinson hammered home an alley-oop pass for an 88-81 bulge with 2:37 left.
"It's a little demoralizing when you play defense for 20 seconds and force a missed shot and the guy just tips the ball back in," Barry said. "They were just doing a good job of taking advantage of their size and knowing that is one of our weaknesses."
On the next possession, Seattle's Desmond Mason had his shot smothered by Duncan. McMillan came bounding off the bench screaming for a foul and was hit with a technical.
"I thought there were a lot of calls that were missed in the game," McMillan said. "They got all the breaks."
After Steve Smith made the free throw, Robinson had a tip-in for a 91-81 lead with 1:53 remaining. But Seattle shot its way back in it.
Vladimir Radmanovic made a 3-pointer and Barry dunked before Radmanovic pulled up for what looked like another 3-pointer. However, his foot was on the arc, leaving the Sonics with a 91-88 deficit with 49 seconds to play.
"We have a little too much size for them and they have a little too much speed and shooting for us," Duncan said. "We're up eight, nine points down the stretch and they hit two threes in a row and makes it into a whole new ballgame."
Parker missed a jumper and Duncan committed a turnover with 16 seconds left before Rashard Lewis missed a layup and a 3-pointer, forcing Seattle to foul with 5.4 seconds to go.
Mason drew an offensive foul from Smith before the ball was inbounded, giving the Sonics one last chance. But Payton's rushed 3-pointer was well off the mark at the buzzer.
"We have a size advantage and they have a quickness advantage," Spurs coach Gregg Popovich said. "Either team could have won the game. It was crazy."
Parker scored 22 points for the Spurs, who blocked seven shots, held a 45-38 edge on the boards and limited the Sonics to 41 percent (31-of-76) from the field.
Payton had 25 points and eight assists for Seattle, which won, 91-90, at San Antonio on November 24. These teams met in the first round of the playoffs last season, with the Spurs winning in five games.
"We thought about that walking in here," Duncan said. "We thought about that when the fourth quarter started and we thought about that when we were up by eight with two minutes left. It's definitely on our mind."
Parker started quickly, scoring 14 points in the first quarter as the Spurs jumped to a 25-21 lead. Payton scored 13 points in the second period, but the Sonics still trailed, 53-49, at halftime.
Seattle trailed, 72-71, entering the final quarter and tied it, 80-80, on Mason's free throw with 5:13 to go.
Smith scored 13 points for San Antonio, which shot 43 percent (32-of-74). Duncan also had eight assists.
Radmanovic scored 17 points, Lewis added 15 and Barry 12 for Seattle.
