I have to give the Sox credit - over the last three games, they've had plenty of opportunities to lie down - and they didn't do it. At the same time, the Yankees lead batters have gone to sleep since the third game.
Tonight's game had some oddities - two calls by the umpires were reversed after huddles (both correctly, as it happens, and both against the Yankees). That's a fairly new thing in baseball - I remember watching games as I grew up, and calls were never reversed - once an ump made a call, it stuck - good, bad, or indifferent. The main problem with the huddle approach is that it slows down a game that desperately needs speeding up.
Either way - the Sox have done what no other MLB team has ever done - forced a seventh game. Either the Yankee bats wake up, or the unthinkable will occur.
