MEMPHIS, AP:

The Memphis Grizzlies secured a berth in the NBA Western Conference semi-finals by beating Portland 99-93 on Wednesday, completing a 4-1 series victory over the Trail Blazers.

Five of the final eight teams in the play-offs have now been decided, while Atlanta took a 3-2 lead over Brooklyn in one of the three first-round series which are yet to be settled.

Memphis' Marc Gasol had 26 points and 14 rebounds to lead the Grizzlies was thrilled with the victory, and the chance for three days off before the conference semi-finals against Golden State which starts Sunday.

In the West semi-finals for the third time in five years, the Grizzlies realise it's time to go further.

"We wanted to go get the job done now, get some days of rest to get ready for the next tough series," Vince Carter said. "This is just a warm-up for the next one, and the next one and the next one."

Memphis closed it out despite not having point guard Mike Conley for a second straight game as he recovers from surgery to repair broken bones near his left eye.

Courtney Lee scored 20 points for Memphis, Zach Randolph had 16 and Jeff Green added 10 off the bench.

Atlanta won 107-97 at home against Brooklyn to take the upper hand in a 1st vs. 8th series that's closer than most expected.

The Hawks can wrap up the series with a victory in Brooklyn tonight Friday, but the eighth-seeded Nets seem intent on taking it to the limit.
