WASHINGTON (AP) -- Gio Gonzalez pitched six innings of three-hit ball to earn his 12th win, Ian Desmond homered, and the Washington Nationals used a three-run sixth to beat the Colorado Rockies 4-1 on Saturday.

Gonzalez (12-3) won his fourth straight start to move into a tie with R.A. Dickey of the New York Mets for the major league lead in wins. Gonzalez allowed one run, walked three and struck out six.

It was the fifth victory in six games for the Nationals, who own the best record in the NL.
