Brian Tallet.
He had a few good seasons as the long man, and I remember him spot starting and throwing 5-6 innings at one time.
But all of a sudden he s*** the bed.
Every single time he came out of the bullpen, he was guaranteed to give up a walk or a run. It was terrible.
It didn't help that he had his own peculiarities, like high scocks, stirrups and a terrible, audible grunt despite not throwing hard at all.
You can sort of deal with that type of s*** if you're a pretty good player. But when you're s***, and you scream attention, then by god you are as annoying as f***.
Look at that game log!
