Jays kinda control their own destiny at this point ( i hate that saying..)
But the majority of their remaining schedule is against teams directly still in the hunt for that last WC spot.
Cle x 3, Seattle x 3, Texas x3, Baltimore x 6 and Detroit x 3. the only dumpster team is Ath x 3 . Reds x 3 to close out the season and while they're a 5th place team in their division, they have only 2 fewer wins than the Jays as they stand today so ... not a pushover. The Royals are an X factor team, they've won 7 straight and the Jays get them for 2 of their next 4 series. Absolutely cannot let them be that sneaky bad team that catches you by surprise.
Basically, the entire rest of the schedule is against teams with similar records as the Jays so they need to separate themselves.
