The Royals traded first baseman Carlos Santana and nearly $4.3 million to the Seattle Mariners for right-handers Wyatt Mills and William Fleming on Monday, clearing the way for Kansas City to bring up hot prospect Vinnie Pasquantino.

Pasquantino was not in the starting lineup against Texas on Monday night because of tight travel schedules, but Royals general manager J.J. Picollo and manager Mike Matheny expect his big bat to be in the lineup regularly.
