Highlights of Tuesday's NBA games

Rockets 105, Thunder 99

Lou Williams scored 10 points during an opening burst in the fourth quarter, and James Harden finished with a team-high 34 points as the Houston Rockets rallied for a 105-99 victory over the Oklahoma City Thunder on Tuesday night to claim their Western Conference first-round playoff series in five games.

Williams opened the fourth with two free throws and added three more from the line plus a deep 3-pointer that pushed the Houston lead to 86-81. The Rockets once again made progress with the Thunder's Russell Westbrook on the bench, holding onto their lead even after Westbrook re-entered the game with 9:09 left.

Westbrook amassed 47 points, 11 rebounds and nine assists but shot 2 of 11 in the final period -- 0 for 5 from behind the 3-point arc -- after carrying the Thunder to the lead in the third. None of his teammates finished with more than 11 points.

Harden shot 16 of 17 from the free-throw line. Williams totaled 22 points, while guard Patrick Beverley added 15 points and eight rebounds. Eric Gordon and Nene combined for 22 points off the bench as Rockets' reserves posted a 44-22 edge over the Thunder's bench.

Spurs 116, Grizzlies 103
