DENVER (AP) — Nolan Arenado homered twice, rookie right-hander Tommy Kahnle picked up his first major league victory and Colorado overcame a four-run deficit Saturday night to beat Arizona 9-4 and send the Diamondbacks to their worst start in franchise history.

Charlie Blackmon went 3-for-4, tying the Rockies’ franchise record with nine hits in consecutive games, a mark set by Juan Pierre in September 2002. After going 6-for-6 Friday, Blackmon singled his first time up, and then grounded out to first base before adding two more singles.

Paul Goldschmidt had his 26-game hitting streak snapped. He went 0-for-2 with two walks as the Diamondbacks fell to 1-7.

Kahnle, selected in the 2013 Rule 5 draft from the New York Yankees, pitched 1 2-3 innings of one-hit ball in relief.
