'''B. Coz''' (full name '''B. Costello''') is a character who appears in the [[Game Boy Color]] version of ''[[Mario Tennis (Game Boy Color)|Mario Tennis]]''. He is on the [[Factory (tennis school)|Factory]] team. Unlike B. Coz's partner (and brother), [[A. Coz]], he can serve and hit powerful shots. The player faces B. Coz in the [[Island Open]]. In doubles, the player faces him in the final round. In singles, B. Coz loses against [[Emily]] in the second round. 

In ''[[Mario Tennis: Power Tour]]'', which takes place several years later, he and A. Coz are revealed to be coaches at Factory. Their younger brother, [[Willy]], is the player's final opponent in the Island Open.

B. Coz's name comes from the English word "because".
