D'backs done in by old farmhand

DENVER (AP) - Carlos Gonzalez homered and drove in two runs, Jorge De La Rosa pitched effectively into the sixth and the Colorado Rockies beat Arizona 4-1 on Wednesday to take two of three from the Diamondbacks.

Gonzalez. a two-time Gold Glover winner, is in his 6th Major League season since originally signing as a free agent with the Diamondbacks in 2002. He spent five seasons developing in the Arizona farm system before being traded after the 2007 season to the Oakland A's in the deal that brought Dan Haren to the desert.

Dexter Fowler had two hits in his first start in the cleanup spot and Nolan Arenado added an RBI double as the Rockies caught Arizona in the standings. The Diamondbacks entered the day tied with San Francisco for first in the NL West.

De La Rosa (6-3) kept up his mastery against Arizona at Coors Field, improving to 8-0 with a 1.38 ERA. He struck out five and allowed six hits in 5 1-3 innings.

Relievers Edgmer Escalona and Matt Belisle bottled up Arizona to get the ball to Rex Brothers, who closed the ninth with Rafael Betancourt sidelined by a groin injury. It was Brothers' first save of the season.
