The Lakers closed the first half of Game 1 of their second-round playoff series against the Dallas Mavericks with a 14-2 run tonight at Staples Center. They played well enough in the opening half, but the Mavericks helped them out with a couple of bone-headed plays inside the final second. First, Jason Terry smacked Lamar Odom on the arm as he attempted a desperation 3-pointer from near midcourt with 0.7 seconds left. After Odom sank three free throws, Dirk Nowitzki cracked Ron Artest with an elbow with 0.4 seconds left and was whistled for a technical. Kobe Bryant sank the free throw to give the Lakers a fourth freebie inside the final second. Bryant scored 15 points and Odom had 11. Terry had 13 points.
