It was the fourth straight win for the Trail Blazers (6-2), who trailed by eight points with eight minutes remaining.

Forward Thomas Robinson came off the bench to lead Portland (56-3) with 15 points to go with eight rebounds. It was a rough shooting night for Portland's top two scorers, LaMarcus Aldridge and Damian Lillard. Aldridge finished with 12 points on 5-for-19 shooting. Lillard, who had 11 points, was 4 for 13 from the field.
Center Robin Lopez collected 13 points and 15 rebounds for the Blazers, who shot only .417 from the field and equalled their season-high with 17 turnovers.

NOTES: Phoenix G Goran Dragic was in the starting lineup after missing the Suns' Tuesday practice session to be with his wife for the birth of the couple's son, Mateo. Dragic, who missed the Suns' previous three games with a sprained ankle, had 26 points, nine assists and six rebounds in a 104-91 season-opening victory over Portland. ... Phoenix, which averages an NBA-best 23.3 fast-break points a game, had 31 in the first meeting with the Blazers. ... The Suns began the night ranked fifth in the league in scoring defense (96.0) and sixth in opponents' field-goal percentage (.430). "Everybody talks about how much they go up and down the court on the offensive end, but they're doing a terrific job defensively," Portland coach Terry Stotts said. "They're doing it with energy and focus." ... When the Suns (5-2) traded veteran C Marcin Gortat before the regular season began, it was assumed the organization was "tanking" the season to position itself for a lottery pick in the draft. "That's what they say," Phoenix coach Jeff Hornacek said. "I told the guys earlier in the season, 'You'll hear that, but you won't hear that from coaches and you know you're not going to hear it from players.' We're all too competitive for that. We're happy with how it's started. but we feel we can still play better."
