No, not necessarily. There is more to hitting a ball hard than simple strength. I bet Gary Sheffield will hit a baseball harder than Warren Sapp, but I bet Warren Sapp could snap Sheff in half.
This is even harder to believe. Look at some of the fastest pitchers coming up nowadays...Tim Lincecum...Justin Verlander...Lincecum's like 5'9" and weighs like 160 pounds, but can throw the ball a **** of a lot harder than David Wells, who's probably stronger than him. There's more to throwing hard than strength.
This list does not mention Donnelly, nor does his

That's the most I could find regarding any cheating by him.
Canseco claims to have used steroids his entire career. Steroids do screw the human body up after prolonged use, which is why his career crashed.
