Evelton McBlase is a blaseball blase given sentience by Our Lady of Perpetual Friday to fill the sudden void in the Fridays' pitching rotation. Following the untimely demise of Solis, catcher Terrell Bradley went to wipe sand off fourth blase only to discover that it had grown a mustache. Evelton soon opened its eyes for the first time and rose out of the beach. "What's the story, morning glory?" said McBlase. "Daddy-o, I've been stuck in that grody sand forever! Come on snake, let's rattle." It then strolled up to the mound and took over pitching duties. The Fridays have not replaced fourth blase and now traditionally mark its location during games using Daddy Bradley's ballcap.
McBlase speaks with a slight transatlantic accent and uses phrasing and terminology that would be more in line with the 1950s than with modern day. One popular fan theory is that McBlase was given sentience using a wandering soul that perished during the '50s and refused to move on to the afterlife, most likely because "the vibe was bogus."
