Mondesi was called up from Triple-A Omaha on Tuesday, Jeffrey Flanagan of MLB.com reports.
Mondesi, generally viewed as Kansas City's top prospect, had been on fire his past 10 games for Triple-A Omaha, batting .359 with eight runs, eight RBI and five steals. Soon to be 21 years old, he'll now be in line to make his major league (regular season) debut, which could come Tuesday against Tyler Skaggs and the Angels. Whit Merrifield was optioned in a corresponding roster move.
