Top 20 players who will shape NL West race

If you can believe it, Opening Day is only four weeks away, and we’re previewing each division every Wednesday. Baseball is an individual sport masquerading as a team sport, so, thus, we’ll be previewing each division by counting down the 20 most pivotal players in the division. These aren’t necessarily the best players. They’re just the ones whose 2018 performance will be most vital to their teams’ success this season, and in seasons moving forward. To keep it fair, we can only pick four players from each team.
