On the contrary I think Dickey gives us just the same chance to win. There is no guarantee we win the first game either. Anything can happen. Jays are the better team, the better team doesn't always win.
So if Astros win and Rangers lose Angels are out and Astros and Rangers are tied for AL West. If Yankees win they get home for WC. If Yankees lose loser of Astros Rangers division game is tied for WC
If Astros lose and Angels win Rangers clinch AL West but there are 2 teams tied for final WC.Yankees get home game
