Bill McCloskey

"Big" Bill McCloskey, also known as Nails, for being a manicurist during off-season,  is one of the members of the Springfield Isotopes baseball team. He was described by Milhouse as the team's clean-up hitter. 

McCloskey played against the Shelbyville Shelbyvillians, eventually scoring the game-winning grand slam after Homer Simpson]] started dancing to cheer the crowd up. Before the hit, the Isotope Stadium play-by-play anouncer called him a "mediocre slugger."
