Geraldo Perdomo singled to left to score Ryan Waldschmidt, then Nolan Arenado doubled to left to bring home both Perdomo and Marte. Colorado answered in the fourth as Troy Johnston singled to right to score Hunter Goodman, and Ezequiel Tovar grounded into a fielder's choice that brought Rumfield home.
