What happened: His previous turn in that spot came in Game 5 of the 2018 World Series, when Boston clinched the title. Eight years later, Sale was back in relief with a postseason berth three outs away, reviving a role Boston had not used with him since that finish.

Why it matters: The appearance matters because Boston used a Cy Young winner outside a standard starting assignment in the postseason. That kind of flexibility can reshape the club's pitching plan deeper into October.

What to watch: Watch whether Sale is held for another leverage spot as the series continues Friday. Any repeat usage would further define Boston's postseason pitching options.
