Red Sox ace Chris Sale takes the mound in Washington with a chance to pitch Boston into the postseason. A win would ensure the Red Sox host Tuesday’s AL wild-card game — they own a tiebreaker with the Yankees after winning the season series 10-9 — but Boston is still assured at least a tiebreaker game Monday with a loss to the last-place Nationals. Aaron Judge and the Yankees are tied with Boston for the top AL wild card and can also clinch a spot by beating 100-win Tampa Bay.
