Royals infielder Raul Adalberto Mondesi pinch-hit for reliever Danny Duffy in the top of the fifth inning against Mets starter Noah Syndergaard. In doing so, he became the first player in baseball history to make his big league debut in the World Series. Mondesi, as many hitters have, struck out against Syndergaard.

Mondesi, 20, spent the entire 2015 season with Double-A Northwest Arkansas, batting .243/.279/.372 with 22 extra-base hits, 33 RBI, 36 runs scored, and 19 stolen bases across 338 plate appearances. He entered the season rated as the #27 overall prospect in the game by Baseball Prospectus, #28 by Baseball America, and #40 by MLB.com.

The Royals added Mondesi to their 25-man roster before the World Series started, taking the place of the speedy Terrence Gore.
