Zach Randolph scored 16 of his 22 points in the first half, rookie Brandon Roy added 19 points and the Portland Trail Blazers beat the Seattle SuperSonics 103-95 on Friday night for their first pre-season win.

Randolph dominated his matchups with Seattle forwards Chris Wilcox and Nick Collison in the first half. He went 6-of-9 from the field and grabbed five rebounds as the Blazers (1-3) shot 61 per cent in the first half. They shot 62 per cent for the game.

Randolph returned in the game's final minutes, as Portland coach Nate McMillan went with his starters to keep the lead. Before the game, McMillan said it was important his young team won in the pre-season.

Seattle pulled within six points early in the fourth quarter, but Randolph, Roy and rookie Ime Udoka combined for 12 straight points as Portland pulled away, delighting Blazers' owner Paul Allen who sat courtside.

Ray Allen led Seattle (1-3) with 16 points, 10 coming in the third quarter as the Sonics' rallied from a 54-43 halftime deficit and briefly took the lead. Most of Seattle's starters played just the first and third quarters.

Luke Ridnour added 13 points, and Rashard Lewis and Damien Wilkins each had 12.

Roy, an All-American at Washington last season, was 4-of-7 from the field and 11-for-12 at the free throw line.

Udoka, a non-roster invitee out of Portland State, added 16 points, 11 in the second half. Udoka scored 16 points on Thursday night against Utah, just two days after his father passed away in Portland.

Reserve guard Juan Dixon added 17 points for Portland.

Allen's baseline jumper with three minutes left in the third quarter pulled Seattle even at 66-66 and Robert Swift's two free throws a minute later gave the Sonics their first lead since 6-5. But Portland scored 10 of the final 14 points of the third quarter and the first seven points of the fourth to push the lead back to 11.
