An occasional Ephus pitch carries tremendous entertainment value.
I love seeing someone throw an ephus. You'd think you'd have AAAA quality players or washed up vets trying to perfect pitches like that more than you do. If you can master a trick pitch you can scrape together a year or two in the majors.
I think kershaw has thrown a few ephus pitches. I would love to see someone like chapman or Thor perfect an ephus pitch. Could you imagine the entertainment value of a guy sitting on the 100 mph FB but swinging at the 55 mph ephus
The splitter is my favorite pitch partially due to Smoltz having a great one and owning people all day long with it. Sadly it caused him injury issues here and there. Clemens had a great splitter as well. Might be that I don't follow MLB as a whole as I used to but I can't really recall anyone since those two that have had that good of a split finger pitch.
If I were a pitcher trying to make a career out of it, I would master throwing the change up and two seamer to compliment my straight fast ball, a la Greg Maddux. Maddux threw a curve too, but it was his 4th pitch, not his 1st or 2nd. I think you could almost guarantee yourself a nice, long, healthy career if you just didn't rely heavily on breaking pitches.
