It's even worse than that. A lot of those guys with 3+ TJs didn't really have that many TJs. For a while there, there were other, similar operations that were being lumped in as TJs. I'm pretty sure that was the case with Isringhausen, Rijo, and at least one of Fox/Williamson. It's been a while since I looked it up.
But yeah, Venters is the only guy with anything resembling any real success after 3 actual TJs. And that really consists of one solid season in relief.
