Eric Hinske. He also has a 3 year WS streak with 3 different teams still alive.

Kazuhiro Sasaki had three solid years in the majors, but only played four total years in the bigs. Yes, he went back home as he was homesick...but I would still mark that as a disappointment.
And Sava, you would be happy to know that Fast Eddie has been out of business for quite a while. I worked for a competitor in the early 1990s and heard a lot of stories about the guy.
That McCovey guy back in '59 took the ROY from Vada in half the ab's. I refused to hear about McCovey ever since! j/k lol :
Bobby Crosby had a decent (albeit shortened) sophomore season, but he has been nothing better than mediocre ever since.
Aside from one season, Jason Jennings has been below average since winning RotY, too.
Pat Listach somehow received NL MVP votes for his rookie season and was only horrible after that year.
I don't know much about Joe Charboneau, but he had less than 200 at-bats after his rookie year, and they were nothing to write home about.
