I think you just answered your own question. My question is what evidence do you have of this other than accusations? The MLB HR rate/AB 2013-2015: 2.77% The MLB HR rate/AB 1955-1960 (pre-1961/62 expansion): 2.64% Now factor in advances in strength training, nutrition, video analysis of pitchers, pitchers throwing harder, ballparks in thinner/higher altitudes (Colorado, Arizona), smaller ballparks (Cincinnati, RF in the new Yankee stadium), lowering the mound, ballparks with retractable roofs (less playing in adverse weather conditions), playing with fewer hangovers because of not going on as many benders the night before... Just citing HR rate is totally irrelevant. If you had actually read my post history you would know that (1) I don't think steroids actually improve baseball performance all that much, (2) I don't personally care one way or the other who is or who is not taking banned substances. I was one of a handful of people on this web forum who consistently defended Ryan Braun since day 1, who does not care whatsoever what Ryan Braun did or not do, and who hates the mainstream baseball press for their ridiculous crusade, so your original accusation is a little confusing. That said, anyone who has any contact with modern athletics, weight training, etc., knows that the use of substances banned by MLB rules is widespread. Testing is an absolute joke because it is only a test for finding which player is stupid enough to screw up his routine for evading the tests (which is what apparently happened with Braun). I don't think modern athletes' physiques are natural, and I find it hard to believe that the majority of them are achieved through above board training alone. Sorry if that shatters any illusions about us still living in a world where baseball players are normal guys who work as mechanics in the offseason.
