Fangraphs wildcard odds gives the Mets and Braves a combined 99.5% chance of taking one spot and the Dodgers and Padres a combined 96.4% chance. I dont know if their odds take into consideration the additions/subtractions each team has made, but it seems fair to assume the first two spots are taken and the Phillies are fighting it out for the final wild card spot with the Cardinals and Brewers.Theres a small outside chance that the Marlins or Giants make a run but realistically its the Phillies vs the loser of the Cardinals and Brewers division race.
Fangraphs likes the Phillies odds, 62.4% vs a combined 35.6% for the NL Central pair. Again, I don't know if the odds factor in the trades, but either way I think we're in scoreboard watching territory and the only teams that matter are the Cardinals and Brewers. They play each other 7 times which is helpful,but they also both play a lot of bad teams, including the Nats and Reds whose rosters are significantly weaker than the ones who established the winning percentages used here.
Being optimistic/grasping at straws the Brewers schedule is close to .500 and both teams games vs the Yankees, Dodgers, Padres and Mets are hopefully early enough that they aren't after the division races are completely wrapped up, while the Phillies final series is against an Astros team who should have the NL West wrapped up by then.
