I can't imagine anyone throwing an 81 pitch complete game anytime soon, or maybe even ever again ?
These complete games will likely continue to dwindle in quantity every year, barring some radical change in the rules/ philosophy of the game.
Currently it is nearly impossible to win 20 games in a season, somewhere around 0-2 guys will do that per year, something like Guidry's 25-3, or something close to that season is not doable any more, maybe it was 25-4 ?, Doesn't matter, that's just semantics !
300 wins in a career, never again !
