Since you posted this twice, a response is due.
Sox payroll is $182M, 11th biggest. But then you have to subtract $17M they are paying Sale to pitch for Atlanta, $7M to Turner, who's also gone, $22.5M for Story who's missed the season, ditto $18M for Giolito, $19M for Yoshida who is out for an indeterminate period and who couldn't hit before then, and $3.5M for Whitlock, who's missing 5/6 of the season. Subtract that $87M, and you have a $95M payroll, of which $29M goes to Devers, and $16M. Both are having good seasons, but that leaves just $50M to pay for 12 of the Sox 13 pitches and 12 of the Sox 13 position players.
By my reckoning, they should have a losing record.
