The AP reports: The Houston Rockets got away with another quiet night from Yao Ming because they forced Brandon Roy into one, too. Luis Scola scored 19 points and the Rockets bottled up Roy in an 86-83 victory over the Portland Trail Blazers on Friday night that gave Houston a 2-1 lead in the first-round series. Yao scored only seven points on 2-for-7 shooting, but Shane Battier scored 16 points as Houston beat the Blazers for the 11th time in the last 12 meetings at the Toyota Center. Game 4 is Sunday in Houston… Roy, who scored 42 points in Portland’s 107-103 win in Game 2, had 19 points, but went 6-for-18 from the field. Even when he broke free from Battier or Artest, Houston’s defense seemed to converge on him in the lane… Steve Blake scored 16 and had 10 assists, and Rudy Fernandez sank five 3-pointers and finished with 17 points for the Blazers, who trailed by 17 in the second half before rallying in the final quarter.
