CLEVELAND, Ohio — Minor league baseball has always been the laboratory for sports marketing creativity, but the Erie Sea Wolves’ transformation into the “Moon Mammoths” might just take the championship trophy for most brilliantly bizarre rebrand of the season.

The story of the Moon Mammoth goes back to 1991 when a scuba diver named George Moon found a nearly three-foot long bone while searching Lake Pleasant in Erie County, Pa., that ended up being the shoulder blade of a very large mammoth from some 12,000 years ago.
