The Jac Caglianone era is underway for the Royals. Tuesday evening, Kansas City's No. 1 prospect made his big-league debut against the St. Louis Cardinals at Busch Stadium after only 79 minor-league games.

Royals top prospect Jac Caglianone went 0-for-5 in his major league debut on Tuesday night, but his presence was enough to help Kansas City overcome a five-run deficit to beat the Cardinals 10-7.

His first four-hit game as a big-leaguer — his first multi-hit game in the majors — arrived Sunday afternoon against the White Sox. Caglianone joined Bo Jackson as the only players in franchise history to enjoy a four-hit day within his first six games. Jackson, who had four hits in his fifth game, did so on Sept. 11, 1986.
