2009 was won on the bat of admitted cheater Alex Rodriguez. The prior run was during the height of the steroid era and feature numerous players that would admit to using PEDs. And that's not including the obvious ones that were to cowardly too admit they cheated. Cough, Roger, cough.
Graig Nettles, star of the Yankees 1977 and 1978 World Series champs, was discovered as a cheat when his bat broke and six superballs came bouncing out.
Whitey Ford admitted to scuffing and using illegal substances on balls when pitching in the World Series. BTW, Ford was on the Yankees World Series teams that won in 1950, 1953, 1956, 1958, 1961, and 1962.
So with a quick google search, I found at least 11 Yankee titles that are tainted by cheating. That's 40% without even breaking a sweat.
Finally:
$100,000 fine for stealing signs you stupid cunt. Your Cashman for Clunkers teams are just too shitty to win when they cheat now.
