The hot-shooting Warriors sank 16-of-30 three-pointers against a porous Wizards defense.
Golden State trailed 61-60 at halftime, but out-scored Washington 63-54 in the second half -- including 33-26 in the fourth period, when Davis and Stephen Jackson combined to make four treys.
Jackson had 28 points and six rebounds, Kelenna Azubuike had 15 points and four rebounds, while Mikael Pietrus and Monta Ellis scored 11 points apiece for the Warriors -- who bounced back from a 105-82 pasting at Boston Wednesday night.
Washington's Antawn Jamison had 30 points and 12 rebounds. Caron Butler recorded his first triple-double of the season, with 26 points, 11 rebounds and 10 assists.
Nick Young scored 18 points, Andray Blatche had 13 points and eight rebounds, and Antonio Daniels added 12 points and five assists for the Wizards, who had a six-game winning streak broken.
