40% of the Mariners remaining schedule is against the Royals, A's, White Sox, and Mets.
The Jays have one "easy" stretch from the 25th to September 10th, and I put easy in quotes because they just split with the Guardians and got shut down by the corpse of Noah Syndergaard so I'm not sure what is easy anymore. After that, they end the season with 4 against the Rangers and 15 against the AL East (Red Sox, Yankees, Rays). The Yankees and Red Sox might be done by then, so maybe they'll be easier to play against.
I don't know. Could go either way. The M's offense might be just as bad as the Jays, and they have a good rotation and pen. They are scary similar. Probably flip a coin on this one.
