Bobby Witt, Jr. may force the Royals to bring him to the majors quickly:

It’s in his speed, his glove, his power to all fields and pure sense of the game. Even his contagious aura and maturity, at least in part primed by being the son of a major-league pitcher, Bobby Witt.

Bringing him to the majors at the start of the season provides some good optics. The Royals set themselves up for this season to be successful. Breaking camp with Witt shows that the team is serious about that, going with their best team now rather than worrying about seven years from now. If Witt is the real deal, the Royals would make a tremendous offensive improvement at a position, SS, where offense is a huge bonus. With all the other off-season moves and Witt at shortstop, the Kansas City fans should be energized.

This is, of course, based on a small sample, but if Witt comes out of the spring continuing to hit well, this should be an obvious move for the Royals.
