Have all been rumored to have dabbled. Ortiz is overweight
Sheff isn't a Yankee, and all his BALCO related stuff was pre-Yankee.
Clemens? No proof of anything other than speculation from writers, just like Varitek and Nixon were called out by Verducci. Except Clemens hasn't undergone the atrophy experienced by the other two.
Ortiz is fat? He's not really fat. Take away the name and the uniform, and tell me how RSN would react to someone who's experienced a huge weight gain from his rookie year, a complete power surge, a power loss, and and a bunch of injuries? Also a player who has made excuses for Dominican/Latin players who HAVE failed, and admitted he doesn't know everything he's put into his body.
Here's Mr. Arias' rookie card, looks a little different than he does now:
Now, personally, I don't really think Ortiz juices, but it's probably easier to make a case than Clemens, whom you labeled a "known juicer".
