A unique piece of baseball history was made during World Series Game 3. Raul A. Mondesi, a 20-year-old prospect for the Kansas City Royals and the son of Los Angeles Dodgers All-Star Raul Mondesi, became the first player in MLB history to make his major-league debut in the World Series. Mondesi's big moment came as a pinch hitter for pitcher Danny Duffy in the fifth inning. The assignment was a difficult one for the inexperienced young star, as he came face-to-face with flame-throwing right-hander Noah Syndergaard.
