On Tuesday, the Colorado Rockies made another move that was a statement to how much change is needed within the bullpen’s performance. For the second time this month, a veteran reliever was designated for assignment. This time, it was left-hander Mike Dunn, who was DFA’d before the Rockies began a critical nine-game road trip through the National League West, with the first stop coming in Arizona against the Diamondbacks on Tuesday night.
Dunn was replaced on the active roster by utility man Pat Valaika. It was no surprise that the Rockies would call up a position player before the nine-game road trip.
