Noah Davis dodged his inevitable baptism by fire, until Saturday night.

The Rockies’ rookie right-hander, so good in his first two big-league starts, was roasted by the Diamondbacks, who ripped Colorado, 11-4, in front of 34,399 fans at Coors Field.

Davis, 25, entered the game with an 0.93 ERA, the lowest in Rockies history for a pitcher’s first two career starts. Davis was also the only Rockies pitcher to not allow an extra-base hit through his first two starts. But it took Arizona just two innings to teach Davis some big-league lessons. He departed having given up seven runs on seven hits with an ERA of 6.17.

Colorado lost its third consecutive game and fell to 8-20, the worst record in the National League, with a run differential of minus-62, also the worst in the NL. Arizona, leaders of the National League West, improved to 16-12. The D-backs outhit Colorado 16-8 and got home runs from Geraldo Perdomo (three-run shot in the first) and Christian Walker (solo blast in the eighth).

Josh Rojas led off the game with a double to right and scored on Corbin Carroll’s single to give Arizona a 1-0 lead.

The Diamondbacks turned the second inning into LoDo batting practice, sending 10 batters to the plate and producing six runs on five hits and two walks. Jose Herrera drew a bases-loaded walk for the first run of the inning, Rojas followed with a two-run single and then Perdomo blasted his 413-foot, three-run homer to right off Davis.

While Davis struggled, the Rockies’ offense scuffled, again, as their home losing streak reached seven games. Colorado has been outscored 69-24 during the home skid.

There were a couple of positives for Colorado. Left fielder Randal Grichuk, back from the injured list, made his first start of the season and was 2 for 4 with singles in the fourth and sixth.

Rookie shortstop Ezequiel Tover brought the crowd to its feet with a one-out triple to right in the fifth.

But, in keeping with the spirit of the Rockies’ season, Tovar was thrown out at the plate trying to score on Charlie Blackmon’s flyball to shallow center. The D-backs’ Alex Thomas made a great throw to nail Tovar.

The Diamondbacks will attempt to sweep the Rockies on Sunday afternoon.
