Durant's 39: Oklahoma City's 7th Thunder

Coming off his worst performance of the playoffs, Kevin Durant couldn't get his shots to fall again. Then he caught a glimpse of his mother dancing around during a timeout and, like magic, the ball started going through the net.

Durant scored 39 points for his best offensive outing of the series and Russell Westbrook had his first playoff triple-double as the Thunder advanced to the Western Conference finals with a 105-90 victory over the Grizzlies in Game 7 Sunday in Oklahoma City.

"I knew she had those dance moves," Durant said. "She used to do it all the time when I was young. She was having fun. I was glad to see that."

Soon enough, he was having fun, too -- and the Thunder is two-stepping into Texas for the franchise's first appearance in the West finals since losing in the NBA Finals in 1996 as the Seattle SuperSonics.

Game 1 against the Mavericks is Tuesday night in Dallas.

Durant followed the lowest-scoring game of his two postseason appearances -- 11 points -- with one of his best. He heated up in the second quarter after the entertaining exchange with his mother, put the Thunder in control late in the third, then put it away with a pair of two-handed slams in the fourth.

Westbrook had 14 points, matched his season high with 14 assists and produced extra possessions with 10 rebounds. It was only the fifth triple-double in a Game 7, according to the Elias Sports Bureau. Larry Bird, Jerry West, James Worthy and Scottie Pippen also accomplished the feat.

Bulls 103, Heat 82: Derrick Rose scored 28 points and Luol Deng contained LeBron James as host Chicago struck first in the Eastern Conference finals, pulling away in Game 1.

Deng had 21 points, hit four three-pointers, had four steals and seven rebounds, and held James to 15 points. James shot 5-for-15. Chris Bosh led Miami with 30 points and Dwyane Wade scored 18.

Carlos Boozer added 14 points and nine rebounds for the Bulls, who outrebounded the Heat 45-33. Joakim Noah had 14 rebounds. -- AP
