The Los Angeles Dodgers are the defending champions, and the San Diego Padres have one of the most dynamic rosters in baseball.
With that type of competition pushing them, the San Francisco Giants have been unyielding.
The Giants haven't had a winning season since 2016, and they were certainly overshadowed by Dodgers and Padres entering this one, but it's been clear for a while that San Francisco needs to be taken seriously. The Giants have won 15 of their last 20 games. Not only do they have baseball's best record, but they're four games ahead of the Dodgers, the next-best team.
