O'Hearn has been promoted and will begin the 2017 season at Triple-A Omaha, MLB.com's Jim Callis reports.
Hands down, O'Hearn is the best power-hitting prospect in the Royals' organization. The first baseman has hammered an average of 21 home runs per season in the minors since 2014. O'Hearn owns an impressive .288/.366/.501 slash line over 325 games at the lower levels, but his 29 percent strikeout rate is an obvious hindrance.
