Todd Helton has spent much of his career sending balls down the left-field line at spacious Coors Field. It was only fitting, then, that he reached a major milestone the same way. Helton doubled for his 2,500th career hit, Michael Cuddyer homered among his four hits and the Colorado Rockies overcame the loss of starting pitcher Tyler Chatwood to beat the Cincinnati Reds 7-4 on Sunday.
