BOSTON — Chauncey Billups hit two free throws with one-tenth of a second left and the Detroit Pistons handed the Celtics their first home loss of the season, 87-85 on Wednesday night.

The Celtics (20-3) had matched their best start ever, also achieved by the 1963-64 team that eventually won the NBA title. Boston had won its first 12 home games, its most since a club-record 17 by the 1957-58 squad.

Billups, who scored 12 of his team-high 28 points in the final quarter, was fouled by Tony Allen. On the previous possession, Billups' turnover gave the Celtics a chance to grab the lead.

Richard Hamilton added 21 points for Detroit (18-7) in a matchup of the Eastern Conference's top teams.
