Dirk Nowitzki made 10 of his first 11 shots and an NBA playoff-record 24 straight free throws on the way to 48 points as the host Dallas Mavericks beat the Oklahoma City Thunder 121-112 in Game 1 of the Western Conference finals yesterday.

Jason Terry scored 24 points and J.J. Barea added 21 points as the Mavericks picked up where they left off in a sweep of the Lakers nine days before. They broke open a tight game with a 13-0 run late in the second quarter and never trailed again, stretching their franchise-record postseason winning streak to seven games.

Game 2 is tomorrow in Dallas, where the Mavs are unbeaten from six games this postseason.

The Thunder - fresh off a seven-game series against Memphis that included a total of four overtimes - led by nine early in the second quarter, then went 6:28 between baskets. They missed 10 shots during that drought and were down by 11 when it ended. They eventually trailed by 16 before clawing within five points with 3:42 left, and six with 48.5 seconds to play.

Kevin Durant followed his 39 points in Game 7 of the previous round by scoring 40, one shy of his most ever in a playoff game. While Nowitzki dominated, Durant's scoring binge merely helped his team stay close.

Russell Westbrook went from a triple-double in his last game to 20 points, three assists and three rebounds. He missed 12 of his 15 shots, including 10 of his first 11. Despite his poor aim, he had taken more shots than Durant at one point late in the third quarter, fueling the critics who say he's too much of a scorer and not enough of a distributor.

The Thunder's big problem, though, was Nowitzki.

Six players tried stopping him, and the big German either shot over them or put them in foul trouble. He made 13 free throws in the third quarter alone. And when Oklahoma City sent a second defender at him, Nowitzki usually passed to the teammate left open.

Nowitzki finished 12 of 15 from the field and a perfect 24 of 24 at the line. He was two points shy of his most ever in a playoff game. He also had six rebounds, four assists and four blocks.
