Magic Number: moot
Even though the Red Sox can tie the Evil Empire in the standings with a win over them today, the EE gets the AL East crown by virtue of having a better record against us this season.
So, here's how it shakes out: Either a Boston win or a Cleveland loss today gives us the wild card spot. If we lose and Cleveland wins, that will force a one-game playoff against Cleveland to determine the AL wild card.
*sigh* And a couple weeks ago I thought we'd be a lock.
