Shav Randolph picked a fine time for the game of his NBA career. The 29-year-old Duke product had 13 rebounds and nine points, just missing his first career double-double, as the Celtics  continued their fight for playoff position with a 118-107 win over the Atlanta Hawks  Friday night at TD Garden. The win drew Boston to within 1.5 games of sixth-place Atlanta in the Eastern Conference race, just two games back in the loss column.

Pierce finished with 20 points, 10 rebounds and 10 assists for the Celtics, who improved to 38-34.
For Pierce, it was his third triple-double of the season and 10th of his career. Another milestone was reached as Terry passed the 1,900 plateau in career 3-pointers, becoming just the fourth player in NBA history to pass the milestone. Terry stands behind only Ray Allen , Reggie Miller  and Jason Kidd . Pierce is fifth with 1,810
