SAN ANTONIO, April 3 (Ticker) -- Tim Duncan wasn't making his shots down the stretch, so he did some other things to help the San Antonio Spurs end their slide.

Duncan found Tony Parker for the go-ahead jumper with 6.8 seconds left and partially blocked Predrag Drobjnak's potential tying drive as the Spurs snapped a three-game losing streak with a 90-88 victory over the Seattle SuperSonics.

Duncan had 30 points on 12-of-26 shooting but did not score in the final 8 1/2 minutes, missing his last three shots and committing a pair of turnovers.

As Duncan struggled, the SuperSonics rallied from a 10-point deficit. They pulled into an 88-88 tie on a lane jumper by Jerome James with 1:52 remaining but did not score again.

Duncan harassed Vin Baker into an airball from the left baseline with 33 seconds to play. At the other end, he took a pass in the low post and immediately was double-teamed by Baker and defensive demon Gary Payton.

"They were double-teaming. We did a better job of spacing down the stretch," Duncan said.

"He did a great job getting rid of the ball," Spurs coach Gregg Popovich said. "When you're double-teamed, the last thing you want to do is take a bad shot. He's an unselfish player."

Duncan calmly passed to the left elbow to Parker, who had missed his first five shots but buried the open 18-footer.

"He's had some good guts for us all year long," Popovich said. "He's made some shots down the stretch. He's never afraid to take a shot."

"If you wanted anybody out there to shoot it, tonight it was Parker," Sonics coach Nate McMillan said. "But he made that one."

Seattle had a chance to tie. Shammond Williams drove the baseline and shoveled to a cutting Drobjnak, but Duncan -- who also had 18 rebounds, nine assists and two blocks -- joined Malik Rose is getting a piece of the shot and the Spurs ran out the clock.

"It was Malik Rose's block at the end," Duncan said. "We had six seconds, so we needed something that would develop quick, like a pick-and-roll, and it was important to get good spacing and avoid the double-team," McMillan said. "It ended up going to Shammond Williams in the corner and that is not what we wanted."

David Robinson had 20 points and nine rebounds and Steve Smith scored 19 points for the Spurs, who had won a league season-high 13 in a row before their slide. San Antonio has won nine straight home games.

However, the Spurs again played poorly in the fourth quarter, which they did during their skid.

"It doesn't matter if we're winning 13 or losing three," Duncan said. "We need to get rolling down the stretch, come out with a lot better focus in the second half of games."

Payton had 24 points, eight rebounds and seven assists for the Sonics (43-33), who are just one-half game in front of Utah for seventh place in the Western Conference. Seattle has lost five straight visits to San Antonio.

"We're OK," Payton said. "We know that we can play with these guys. Sometimes things just don't go your way."

The Spurs led by 15 points late in the third quarter and still held an 85-75 advantage after Danny Ferry's 3-pointer with 7:15 remaining. The Sonics scored 13 of the next 16 points as Payton and James had two baskets each.

Seattle shot 57 percent in the first half and opened a 54-45 lead before San Antonio roared back in the third quarter. Robinson scored 13 points and Duncan 12 as the Spurs opened a 76-61 lead with 3:08 remaining.

"I love to pass to David to find him and get him rolling," said Duncan, who set up Robinson with several lob passes. "It gets his confidence up and gets our team rolling. Just put it up there and get the crowd into it."

Duncan also gave Seattle guard Brent Barry five stitches over the right eye with an inadvertent elbow. However, the Sonics closed the quarter with an 8-0 burst, then continued the rally in the fourth quarter, when Barry returned.

The Spurs shot 49 percent (37-of-76) and held a 42-34 rebounding edge. Baker scored 14 points, James added 12 and Barry 11 for the Sonics, who also shot 49 percent (39-of-79).
