The AP reports: After sitting out two games with a sprained right shoulder, Jamison returned to score 27 points as the Wizards ended Boston’s seven-game winning streak and became only the second team to win the season series against the Celtics. Jamison left no doubt that he was again full throttle by making 8 of 17 field goals, grabbing 11 rebounds and ramming home a one-hander over Garnett to cap a 10-0 run that gave the Wizards the lead for good early in the third quarter… Caron Butler had 13 points, 10 assists, seven rebounds and seven turnovers for the Wizards, who handed the Celtics’ their second-worst loss of the season. Washington, which beat Boston in back-to-back games in January, joined Orlando as the teams to win the season series against the Celtics. Paul Pierce scored 28 points, and Kevin Garnett had 22 points and 14 rebounds for Boston, which had 21 turnovers and allowed the Wizards to shoot 51 percent.
