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.

Loftin set the tone for the inning. The Royals followed suit with four consecutive singles as Bobby Witt Jr. added to his RBI total. Witt, who homered in the second inning, added his third and fourth RBIs of the game.
