Ray Fosse and Glen Kuiper are the voices of the Oakland A's on the CSN television broadcasts, but every year since 2012 fans have been treated to a special alternate voice for 20 broadcasts. We've seen Hattie, Shooty, and Chavy step in to provide color commentary next to Kuiper's play-by-play, but this year the new guy is former pitcher Mark Mulder.
Mulder has one thing that Hattie and Chavy lacked: past TV experience, thanks to his time on ESPN's Baseball Tonight. Unfortunately, I didn't plan this paragraph very well and I don't have any other related facts.
