OKLAHOMA CITY — The Lakers were no-shows in the first half tonight and the young, energetic and frenetic Oklahoma City Thunder made them pay. Russell Westbrook, a former UCLA standout, scored 17 points on 8-for-11 shooting. Kevin Durant added 13 points on 6-for-11 shooting. Lamar Odom led the Lakers with 12, and Kobe Bryant had 11. The Lakers shot 15 for 40 in the first half (37.5), which was an improvement on their 6-for-20 shooting in the first quarter (30 percent). The Lakers have won 12 in a row over the Thunder/Sonics, a streak which seems destined to end tonight.
