The AP reports: Up by 29 points in the fourth quarter, the Cavaliers blew most of their big lead against Detroit’s reserves and LeBron James had to go back in and restore order as Cleveland held on for a 94-82 win on Tuesday night to take a 2-0 lead in their Eastern Conference playoff series. For three quarters, the Cavs were at their basketball best… James, showing no regard for a defensive plan Detroit spent three days preparing for him, scored 29 and Williams added 21 as the Cavaliers withstood a stirring comeback by the Pistons, who used a 27-5 run to close within seven on Antonio McDyess’ jumper with 3:51 left… Delonte West scored 20 and Zydrunas Ilgauskas 12 for the top-seeded Cavs, who led 79-50 in the first minute of the fourth and were embarrassing the Pistons. But Detroit dug down and gave Cleveland and its raucous crowd a scare the Cavs may never forget… Richard Hamilton scored 17 and Rodney Stuckey 14 for the Pistons, who are going home down 0-2 with their starters searching for positives.
