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

According to the Interdimensional Rumor Mill, some things never change, even across dimensions. Someone, somewhere, decided to catalog all the different versions of Rat Mason in a Rumor Registry, but today the version from IF-10.332 is playing. Here’s what the rumors say...

Mech Suit Mason

Rat Mason (née Polk) dreamed of being a Broadway star, but their diminutive stature left them frequently stuck at the end of the chorus line. After making friends with the technical crew to pass the time, Rat became adept at creating elaborate mechanical costumes, and soon graduated to full-body suits which completely obscured the wearer. Over time, Rat amassed an impressive and diverse collection, which they began wearing all over New York, delighting in the simple pleasures of performing normal-sized tasks like riding a rollercoaster or climbing a ladder. After a moderate disagreement about the destructive capacity of these suits (which is yet unknown), Rat decided to abandon the theatre and the Big Apple entirely, setting their sights on Los Angeles and the emerging splort of Blaseball.

Since joining the Tacos, Rat has rarely been seen outside one of their suits, and only by teammates and close associates. The appearance of Rat’s suit varies from game to game, but is typically modeled after humans, rats, or some combination of the two. This has led to wild speculation among the general public as to who (or what) is actually piloting these things. When asked who was inside the suits, McDowell Mason replied, “That's [Rat's] business, not yours,” and quickly walked off. Reports of Rat maintaining an armory of mechanized suits in their basement are unconfirmed at this time.

Many Blaseball fans theorize Rat to be either a human in a mechanical rat suit or a rat in a mechanical human suit. The former is supported by a few details from their past. In a series of interviews conducted by an investigative journalist from a local middle school’s bi-monthly newsletter, Rat’s old friends from New York described him as “shy,” “really, really, like comically small,” and “no not a literal rat, what in the world are you talking about.” They also disagreed over whether Rat was Mason’s actual first name, with some referring to it as nickname and one particularly confused woman claiming it was short for “Ratrick.”


Mason has missed the exit from the 405 to the 101 several times.

Mason reportedly wears jersey number 69.
