Seeking serious steroid speculation

As highlighted here, one of the many big stories coming out of the recent British Open was Gary Player's assertion that "I know for a fact that some golfers are doing" some form of steroids. As detailed here, Player said he believed no fewer than 10 professional golfers from around the world were using performance-enhancing drugs, but thereafter refused to name any names.

Taking up where Player left off, I wonder if any Golf Blog readers might want to name names of professional golfers they might seriously suspect of having used performance-enhancing drugs.
