It’s safe to say that the Dodgers and Rockies do not need any introductions. The two teams have had their fair share of battles over the last few seasons and in 2018 they played a game 163 to decide who would take home the NL West title. The Dodgers ended up winning that game and eventually went on to win another National League pennant. The Rockies won the wildcard game against the Cubs before losing to the Brewers.
This season the Dodgers and Rockies are the two main contenders for the NL West title yet again. While the Diamondbacks were in the hunt until the end last year, they have gone into a rebuild of sorts.
