Question: the boy who batted 1000?
Answer: The Kid Who Batted 1.000 is a 2002 book by Lee Gruenfeld writing under the pen name of Troon McAllister. The conceit here is the same, except that the teen protagonist, rather than being the unschooled but naturally athletic country bumpkin Dave Smith, is an unathletic pencilneck bound for MIT, Marvin Kowalski.
