SEATTLE - Tony Parker scored 12 of his 20 points in the fourth quarter, and the San Antonio Spurs improved upon the best road start in franchise history with a 98-78 win over the Seattle SuperSonics on Sunday night.

The Spurs improved to 7-0 on the road and are the only unbeaten road team left in the NBA. San Antonio is the fourth team in the last 10 years to start 7-0 or better on the road. The Spurs will be tested twice more on their current three-game road trip — Monday night at Golden State and Wednesday in Utah.

Tim Duncan added 18 points and 16 rebounds and Fabricio Oberto had 16 points for the Spurs, who have won 12 straight regular-season road games dating to the end of last season.

Ray Allen led Seattle with 21 points and Nick Collison added 15 off the bench.

With the Sonics’ defense focused on stopping Parker and Duncan, Oberto dominated his matchup with Seattle’s Johan Petro, scoring San Antonio’s first 10 points of the second half. Oberto scored off perfect passes from Duncan and Parker, then knocked down a 9-foot jumper as the shot clock expired to give the Spurs a 57-41 lead two minutes into the half.

Even with Seattle’s defense doing its best to slow Duncan, the eight-time All-Star made team history. He became the third Spurs’ player to eclipse 15,000 points in his career, joining David Robinson and George Gervin. Duncan needed 10 points, and reached 15,000 when Collison was called for goaltending on Duncan’s short jumper with 2:05 left in the first half.

The Spurs were without Manu Ginobili, bothered by a lower back contusion suffered in the third quarter of Friday’s loss against Dallas. Brent Barry picked up some of the scoring slack with all 12 of his points in the first half.

Down eight to start the fourth quarter, Seattle scored eight of the first 11 points to pull within 74-71. Parker then re-emerged, scoring 10 points in a 13-2 run that turned the close game into a rout.

Luke Ridnour added 11 for Seattle, including a basket from his knees in the third quarter. Ridnour lost his footing driving into the lane, gained control of the ball and tossed in a 5-footer. But Rashard Lewis was quiet, held to a season-low eight points, 15 below his average.

The 78 points were a season-low for Seattle.

Notes: Seattle fell to 2-5 at home. ... Spurs’ coach Gregg Popovich doesn’t expect Ginobili to play Monday in Golden State, but is hopeful he’ll be ready for Wednesday’s game in Utah. ... Two other teams in the last 10 years started 7-0 on the road — Dallas in 2002 and Indiana in 2003. Houston started 8-0 in 1996. The NBA record is held by the New York Knicks, who won their first 12 to start the 1969-70 season.
