Los Angeles’s Anthony Davis, left, and Detroit’s Andre Drummond grapple for the ball during the first half Sunday. LeBron James had 21 points, 14 rebounds and 11 assists, and Davis had eight of the Lakers’ 20 blocked shots in their fifth straight victory, 106-99 over the Pistons. Derrick Rose scored 28 points and former Lakers guard Svi Mykhailiuk had 14 — one off his career-high — for the Pistons, who have lost nine of 11.
