In fact, since STATS Inc. began recording such statistics in 1974, Perez is only the fourth catcher to snag five or more popups in a game.
The others were the Cubs' Keith Moreland, who caught six on June 13, 1982; the White Sox's Jim Essian with five on July 7, 1976, and the Mariners' John Marzano with five on June 11, 1997.
Starting in Thursday's 4-1 loss to the Rays, Perez caught two more popups.
Perez's callup makes the Royals the rookie leaders in the Major Leagues. He became the 15th rookie to play for the club this year, one more than the Rays and the Astros.
