Dealing with a three-game losing streak, and struggling against a troubled team, Kevin Garnett and the Boston Celtics turned to their defense to pull out a victory. The Washington Wizards thought the Celtics got some extra help from the referees. Garnett's 19 points led six Celtics in double figures, and Boston limited Washington to 2-for-18 shooting in the fourth quarter en route to a 99-88 victory over the host Wizards on Monday night. "You're playing against the Boston Celtics, so you're not going to get a lot of calls. KG's going to set illegal screens; they're not going to be called. That's just part of the game," Wizards center Brendan Haywood said. "You're going to go to the basket, and if it's not basically just a straight-up WWF body slam, you're not getting the call." Both teams took 36 foul shots. Washington was called for 24 personal fouls, one more than Boston. Wizards co-captain Antawn Jamison was whistled for five fouls in the fourth quarter alone on an all-around rough night that started with his left knee feeling badly during warm-ups. He scored only eight points - 13 below his average - and shot 2-for-17 on field goals, 0-for-9 in the second half. He made four of six free throws. The Wizards led by eight points late in the third quarter, but the Celtics used a 16-4 run capped by Rasheed Wallace's 16-foot fadeaway jumper to go up 86-82 midway through the fourth. Boston outscored Washington 25-10 in the final quarter, even though All-Star forward Paul Pierce sat out the period with what he said he thinks is a mild sprain to his left foot.
