Interesting. While you always prefer a home game over a road game, assuming that we concede WC1 to Boston and have the Jays fight for WC2, both this year and historically, the Jays have done much better at Fenway than at home versus Boston:

The Jays have a 43% win percentage historically at home against Boston but 46% at Fenway. What's really interesting (and irritating) is despite the 158-186 record in Fenway, the team has a positive run differential all time. 5.0 runs for versus 4.9 runs against. Much better than the home differential of 4.5-5.2. The last 2-3 years when this team has had a similar roster shows much the same. Better record at Fenway, better run differential, more runs per game. I guess it's because this team and the Jays teams that have proceeded it are built for Fenway. Right handed power hitters.
