Final Score: San Antonio 106, Portland 75

San Antonio, TX (Sports Network) - Tim Duncan scored 18 points, pulled down 13 rebounds and blocked four shots in San Antonio's 106-75 blowout of the Portland Trail Blazers at SBC Center.

Tony Parker also scored 18 points and dished out seven assists, as the Spurs won their fourth straight game and beat the Blazers for the ninth time in the last 10 meetings.

"It was a great defensive effort overall," Duncan said. "We had a solid night defensively and that helped keep their score down. We are starting to get things worked out."

Jarrett Jack had 15 points to top Portland, losers of four in a row. Juan Dixon added 12 points, but the Blazers shot just 37.1 percent from the field and were outrebounded, 57-30. Portland made just three shots in the last quarter, when the Blazers were outscored, 28-11.

"When it's difficult for us to score, we just can't dig down and scrap," Portland head coach Nate McMillan said. "It should be opposite. We talked about pulling together. It's easier to be together when things are going well, but when things go bad that's when you need to pull together. And I don't see us doing that out on the floor during the rough times."

Eight straight points by the Spurs extended them to a 26-18 lead. Duncan's hook shot capped the spurt with 1:01 left in the first quarter, and San Antonio led 28-22 going into the second.

The Spurs led by as many as 13 in the second following a Parker layup before settling for a 53-42 lead at the break.

Two free throws by Steve Blake pulled Portland within 55-47, but Duncan's tip in capped seven straight ensuing points by the Spurs and they held a commanding 78-64 cushion going into the fourth.

The futility continued for Portland, even with the Spurs' reserves in most of the final period.
