The Dodgers open their first trip of the year in Arizona on Monday night, when Hyun-Jin Ryu opposes Taijuan Walker in a 6:40 p.m. PT start to begin a three-game series. In Game 1 of last year's National League Division Series, the Dodgers sent nine batters to the plate against Walker in the only inning he pitched, scoring four runs, three on a Justin Turner homer.
