I think the Wild card will be from the East or the West. Dodgers coming on strong, Philly and Florida both +15 over. The problem with the Central is no team has been that high all year. The Cards play the Astros 6 more times and could beat each other up paving the way for the Cubs to win the division. The Cubs play nobody with a winning record the rest of the year.
Dodgers may be the best bet. Don't know their schedule off-hand but TBS last night said Philly, Atlanta, and Florida played each other home and home yet.
