PHOENIX — Eduardo Rodriguez dominated for seven shutout innings, and Corbin Carroll smacked a walk-off single to right field on Thursday, giving the Arizona Diamondbacks a 2-1 win over the Colorado Rockies to open a four-game series. This was the second walk-off win of the week for the Diamondbacks and third of the year. Ketel Marte hit a game-winning home run on Tuesday, as Arizona’s top two hitters have come through in the clutch during this homestand.
