After the current series against Washington, the Jays' next nine games are at Colorado Rockies and Oakland A's, then three at home against the KC Royals. Following that is four at home against the Texas Rangers, three at home against the Red Sox, and six against the Yankees and five against the Rays to end the regular season. Personally,I would wait until after the series with the Rangers before declaring this season to be a write off, if they're not within a game of a Wild Card berth.
Seven of the Rangers' last ten games are vs the Mariners, and they also have three to play against Houston.
Seventeen of Seatle's remaining games are against the Rangers, Astros, Rays and Dodgers, with three more against the Reds.
