Rockies Rookie Starters Step Up

The Rockies remain a game ahead of the Diamondbacks in the race for the top wild-card spot — and the home field for the one-game wild-card playoff game that kicks off the post-season — and 5 1/2 games in front of the Cardinals, who are third in the wild-card standings.

And the success starts with the Rockies rookie starters.

Tyler Chatwood

Not to discount the Rockies offensive efforts, but the Rockies have had elite offensive players in the past. But among the seven starters the Rockies have used this season are four rookies and two other pitchers who were rookies a year ago. Tyler Chatwood, now in the bullpen, is the most experienced of the seven.

Oh, there is some inconsistency with youth, but it has been minimal with the Rockies rookies. They have had their games they would rather forget, but they have been dominate in the other games, and the games to forget have been minimal.
