A transplant to Los Angeles from New York, Mason was an aspiring dancer before he surrendered to the call of professional blaseball. He is known for batting with his right hand but throwing with his left. When not on the field, he is often found in the back of one of the numerous taco trucks that surround the Tacos' stadium.
Mason lives in WeHo (The City of West Hollywood) with his husband Penny Polk, an LA native. The premiere Splorts Tabloid, the Blaseball Enquirer, has published a series of rumors that the couple are considering a divorce, citing that Polk has never been seen at one of Mason's games. Neither Mason nor Polk has commented on whether the divorce rumors are true.
The Many Faces of Rat Mason
Appearance as a Rat Piloting a Human-Sized Rat
Many have speculated that Mason is not actually the human-sized rat who goes by Rat Mason but instead is a rat who lives under his Blaseball cap and is, to quote social media, "piloting this [respectable] [fellow] Ratatouille-style." Tacos management has not confirmed this rumor due to a respect for Mason's privacy. When asked about these rumors, Manager Al Pastor said, "Sure we've never seen our boy Rat without his hat on, but we think it's like, totally chill if he's actually a rat who dreams of being a splorts star. Like they say: Anyone can Blaseball."
When pressed by reporters, an anonymous source who looks exactly like Mason but without a head had this to say: "Sure, I may or may not lose my free will to yanking on my hair while on the field, but hey; it sure is fun getting to play Blaseball in front of all those screaming fans".
Mason has missed the exit from the 405 to the 101 several times.
Mason reportedly wears jersey number 69.
