As mentioned by others, the September schedule is difficult including series with the Braves, Astros, Guardians, and 6 games with NYY, all likely playoff teams . But prior to the final 3 games with NY at Fenway, there is a 3 game set with the Orioles and a day off. Therefore and depending on what the standings are, Cora can reset the pitching rotation to lineup the best 3 vs NY, obviously including Sale and Porcello. The question will be if Price is in that mix for a critical game vs. NY
Sox also have Jays and White Sox in September, but overall it will be a tough finish line to reach leading the AL East.
