I just checked something.
If the rotation and schedule goes as planned, Halladay is scheduled to pitch in Atlanta on Sunday, Oct 3. (The final regular season game).
Given that Philly and Atlanta have been close for about a month now, that game could decide the NL East title (or lead to a one-game tiebreaker) and possibly even best overall NL record.
In the last 3 Philly NL East title runs, they benefited from 2 NY Met meltdowns in 2007 and 2008, and no serious competition last year. Atlanta is for real, and the NL East will likely go down to the final day.
I want to thank the Blue Jays once again for trading Halladay to Philly!!! :)
