PHOENIX — Playoffs or no playoffs, the Rockies’ 2018 season will be remembered for the emergence of two starting — or is that starring? — pitchers. Left-hander Kyle Freeland, 25, and right-hander German Marquez, 23, have become two of the best young hurlers in baseball. The duo has combined for 41 quality starts (22 for Freeland, 19 for Marquez), 28 victories, 293⅔ innings pitched and 373 strikeouts. Freeland, 15-7 with a 2.95 ERA, has garnered more national attention, but Marquez’s firepower and mental toughness on the mound make him a possible future ace. “Go to his game log since the all-star break,” manager Bud Black said Saturday of Marquez before the Rockies played the Diamondbacks.
