All five of Washington's starters scored in double figures in the first three quarters, a feat they previously had accomplished only once in 16 complete games.

Antawn Jamison had 20 points and 12 rebounds for Washington. Caron Butler added 14 points, nine rebounds and seven assists for the Wizards, who built leads of 20 points in the first half and 31 in the third quarter.

Dirk Nowitzki, who led Dallas with 27 points, capped a 19-6 run with a 3-pointer that pulled the Mavericks to within 102-95 with 1:07 remaining. Devin Harris scored nine points during the tear and finished with 14. Jerry Stackhouse and Devean George also scored 14 points for Dallas.

The Wizards went on a 17-4 run to open the third quarter, capped by Jarvis Hayes' 3-pointer for a 76-45 lead with 6:24 remaining in the period.

A sequence earlier in the period epitomized the game. Arenas banked home a 3-pointer off the glass that gave Washington a 69-45 lead and Nowitzki's ensuing jumper at the other end drew nothing but glass.
