New York Yankees star Aaron Judge stood at his locker prior to Tuesday’s series opener against the Kansas City Royals at Kauffman Stadium. His eyes told the whole story. Judge beamed with emotion when he heard Jac Caglianone’s name. And his signature smile confirmed that elation.

In doing so, Calgianone joined Bo Jackson as the only players in Royals history to record a four-hit game within their first six games as a big-leaguer, according to MLB Pipeline. The 22-year-old recorded three singles and a double in Sunday's win. After a slow start through his first five games, he was dialed in at the plate against the White Sox.

Jac Caglianone’s Royals promotion has been called into question by former Miami Marlins president David Samson. While many Kansas City fans were elated that Caglianone, MLB.com’s No. 10 prospec t, was promoted to the show, Samson had the complete opposite reaction.

Perez atoned for his mistakes on Sunday. He led the way with an early home run as the Royals salvaged a 7-5 win in the series finale. There were other heroes, too: Jac Caglianone belted four hits — his first multi-hit game in the major leagues — and Bobby Witt Jr. hit his eighth homer.

Kansas City Royals phenom Jac Caglianone combines incredible power at the plate with a risky approach, so what's his MLB ceiling?
