How many Yankees are on roids this year?

I watched an interview with Curtis Granderson before the season started and he said he worked on his swing all offseason with the hitting coach, a lot like Jose Bautista did which is why he has so much power. As for Colon and Garcia, I have no idea. It has to be a fluke, because they are too old and past their prime, and it's near impossible to get away with roids these days.
