BOSTON (AP) -- Pau Gasol blocked Ray Allen's putback attempt at the buzzer in overtime and the Los Angeles Lakers held on to beat the Boston Celtics 88-87 last night. Gasol finished with 25 points and 14 rebounds, and Andrew Bynum had 16 points and 17 rebounds to help the Lakers snap a two-game losing streak. Allen scored 22 points and Kevin Garnett had 12 points and 12 rebounds for Boston, which had won five in a row and nine of its previous 10 games. But Garnett was 6 for 23 from the field and Paul Pierce was 7 for 18, including a clean-look jumper at the end of overtime. It rimmed out and Allen tried to push the rebound in, but Gasol got his fingertips on it and it floated away as the buzzer sounded.
