The Philadelphia 76ers ground out an 82-75 win over the Boston Celtics on Wednesday to force a deciding Game Seven in their Eastern Conference second-round play-off series. Philadelphia\'s victory was far from pretty, but they avoided elimination with a gritty effort to tie the best-of-seven series at 3-3 and set up the decider in Boston tomorrow. \"I think it\'s going to be crazy, especially being there in Boston,\" said 76ers point guard Jrue Holiday, who led Philadelphia with 20 points. \"We need to go in there and get this win. I\'m looking forward to it.\" Elton Brand added 13 and ten rebounds for Philadelphia, who are on the brink of springing another postseason upset after eliminating top seeds Chicago in the opening round.Boston\'s Paul Pierce recorded 24 points and ten rebounds while Kevin Garnett had 20 and 11 but no other Celtics player scored more than nine and they finished with just 33 per cent shooting from the field.
