Rockies Home-Grown Rotation Handling Coors Field Challenge

After a quarter of a century of experimentation, the Rockies are comfortable with the fact that they are better off with home-grown pitchers in the rotation than trying to lure established veterans.

The players who come up through the system don't have a baseball card with established numbers that can get blurred by the challenges of Coors Field.

The players who come up through the system want to prove they aren't intimidated.

And this year, they have turned to the home-grown approach more than ever. The Rockies, who along with the Astros are the only MLB teams to have used only five starting pitchers so far this year, have four home-grown members of their rotation. And the fifth, German Marquez, pitched in the minor-league system initially after being acquired from Tampa Bay along with left-handed reliever Jake McGee in the Corey Dickerson trade.

The Rockies go into a three-game series at Philadelphia Tuesday night with a .535 winning percentage for their rotation, which would be the third best in franchise history. The Rockies rotation has had a winning record in only five of the franchise's first 25 seasons, including all four seasons in which they have gone to the post-season.

A look at this year's rotation:

Kyle Freeland, 1st round draft choice, eighth player selected overall, 2014. Denver native. Attended Thomas Jefferson High School and University of Evansville. Career ERA at Coors Field 3.52, lowest of any pitcher with at least 10 starts. 

Tyler Anderson, 1st round draft choice 2011. Grew up in Las Vegas.  Attended University of Oregon, which re-started college baseball Andeson's freshman year. Career ERA at Coors Field 3.73, third lowest of any pitcher with at least 10 starts, just behind Ubaldo Jimenez (3.67).

Jon Gray, 1st round draft choice 2013, third player taken overall. Grew up in Shawnee, Okla., and attended University of Oklahoma. Career ERA 4.88 at Coors Field, 15th lowest pitchers at least 10 starts. Career record 15-7, .682 winning percentage at Coors Field, sixth best franchise history at least 10 starts.

Chad Bettis, 2nd round draft choice 2010. In his return from testicular cancer, Bettis has no decision in six starts at Coors Field this year, but in his career as a starter he is 13-7 at Coors Field and the Rockies are 25-14 in games he has started.

German Marquis, acquired from Tampa Bay along with Jake McGee, in the Corey Dickerson deal in January of 2016. Split the 2016 season between Hartford (21 starts), Albuqueque (five starts) and the Rockies (three starts, three relief appearances). Stepped into rotation last year and was 11-7 with a 4.39 ERA in 29 starts.
