Whats the deal with Jason Albert (Tensai)?

From what I've heard, he has a nice future ahead if he keeps this up

"jason albert"

why wont they just call him matt bloom, his actual name?

They seem to have an affinity for renaming guys and giving them two first names.

I never understood why announcers needed character names.
