The AP reports: After winning their first playoff game in six years, the Portland Trail Blazers couldn’t help but be a little amazed with their victory over the Houston Rockets. “We kind of laughed about it, `Man, it’s hard winning games in the playoffs. It takes a lot of work,”’ said Brandon Roy, who had 42 points in Portland’s 107-103 victory Tuesday night. The playoff series, now even at a game apiece, moves to Houston for Game 3 on Friday. Aaron Brooks led a late charge and finished with 23 points for Houston, which has not made it out of the first round since 1997. Von Wafer came off the bench to add 21. LaMarcus Aldridge had 27 points and 12 rebounds for Trail Blazers, who had never dropped the first two games of a playoff series at home and played one of their most physical games of the season… Rockets center Dikembe Mutombo injured his left leg in the first quarter and left the court on a stretcher.
