OKLAHOMA CITY (AP) -- Brandon Roy couldn't get his shot going for a second straight night. So, he used what energy he had left for one final charge.

Tuckered out after a 42-point performance the previous night, Roy scored 16 and got aggressive late to finish out the Portland Trail Blazers' 83-74 win against the Oklahoma City Thunder on Sunday night.

"I was tired. The first back-to-back is always tough," said Roy, who had 42 a night earlier in Houston. "I just kept telling guys, `This is when we have to execute. This is when we have to almost be perfect."'

Roy struggled to get anything going on offense -- and so did Kevin Durant, a fellow Rookie of the Year.
