Concerns that the Lakers’ bench would be run off the end of the floor by their Phoenix Suns counterparts proved unfounded in the first half of Game 1 of the Western Conference finals tonight at Staples Center. Lamar Odom erupted for 15 points and eight rebounds and the Lakers’ backups outscored the Suns’ reserves, 22-13. Odom couldn’t be stopped on drives to the basket, making 7 of 9 shots. Jordan Farmar added five points and Josh Powell rebounded a Kobe Bryant miss just before halftime and dunked. The Lakers led most of the way after going on an 18-4 run to end the first quarter. Their biggest lead was 11 points.
