I have a player in mind. Your job is to guess who he is. To help you guess, you can ask me questions. But, only objective questions and only questions that can be answered Yes/No.
You have to get the answer within 20 questions to win. All questions, whether good or bad, count towards the 20 total. So, be careful to word your questions correctly.
Congratulations to bstar, who solved the quiz on the 10th question. The hints were a 10-year player who played entirely since 1961 and who ranked first (best) in one career statistical category and last (worst) in another, both among players who played only in 1961 or later. The answer is Greg Minton, who played from 1975 to 1990, and ranks first in HR/9 ratio and last in SO/BB ratio (both for min. 1000 IP) among pitchers who have played only since 1961.
