As someone who has taken both HGH and Steriods (at separate times) as prescribed by my doctors for health reasons, I can tell you you are very wrong about this.
Steroids made me significantly stronger and clearly would have been more effective as a performance enhancing drug, but HGH turned me into an overall better athlete. I lost nearly all of my body fat, gained muscle (not nearly as much as when on steroids, but it was noticeable) and was significantly quicker with my reflexes and faster as a runner. As soon as a stopped using HGH, I gained fat, lost muscle and became much less athletic. The before and after pics of me are striking in their differences.
Now, I imagine it would have less of an effect on a professional athlete, who was already in great shape, and already a great athlete, but I also imagine it would make some difference in their overall athletic ability. As a former HGH user, I can testify that it absolutely would enhance anyone's performance as a baseball player.
