Erika Monroe Williams
The last member of the "actually married to baseball player at this point in time" club, Erika is the wife of retired third baseman Matt Williams and a former Phoenix-area news anchor. She's reportedly popular in the social circles of baseball wives, so we're kinda getting a "queen bee" vibe from her—she's even an admitted to being a control freak, and the ones who like to lead always are.
We're banking on her causing a few issues with the rest of the gals in an effort to assert her rule. Apart from Chantel, Erika seems to be the only other gal who's a "veteran" to the baseball wifey life, so we can only hope this'll somehow come up on the show.
