Due to the Celtics 88-99 win over the Pacers on Monday, the Celtics have extended their winning streak to 13. Paul Pierce had a triple-double with 18 points, Nate Robinson and Glen Davis also picked up 18 points. The Celtics look to extend their streak Wednesday as they face the Philadelphia 76ers at 07:30pm ET. By the way, the Celtics longest winning streak occurred in the 2008-2009 season as they won 19 in a row, it ended against the Lakers (of course).
