LoDo, we have a problem. An ongoing problem to be precise. Playing at a hitter’s paradise, better known as Coors Field, the Rockies’ offense continues to underperform. The Rockies had nine mostly empty hits in a 5-2 loss to the Cardinals on Wednesday night. They were 1 for 6 with runners in scoring position and struck out 11 times. Fireworks came late with Brenton Doyle’s leadoff homer in the ninth off lefty reliever Matthew Liberatore.
