Zack Greinke made his spring debut Wednesday in the Royals’ 8-4 win over the Rockies throwing three innings and allowing just one unearned run in his first appearance after returning to the Royals on a one-year deal last week.
On Wednesday, he and catcher Salvador Perez also debuted some new technology that the Royals and other teams are trying out across Spring Training: PitchCom, a pitch-calling system that could help improve the pace of play and eliminate illegal sign-stealing. Manager Mike Matheny spoke highly of the device late last week and introduced it to some of his pitchers and catchers during workouts on the backfields.
Wednesday was the first time the club used it in a game, with Greinke and Perez using it for the first three innings.
