I remember both Earl Wilson and Mike Hampton well. The guy [pitcher] who could really hit and he did it consistently over a pretty long career was Terry Forster.
A guy who was an all NCAA DH and great college pitcher was Tim Lollar. I thought he was headed for stardom as a MLB pitcher but his career fizzled. He could really hit though.

I thought this topic might be interesting because I didn't come away with any ready made search results for lowest BA with at least 100 HRS. I did manage to see a search result for the worst hitters with 400 HRs. We all know who the king of that category must be.
