The Royals made a flurry of roster moves on Friday, promoting pitchers Matt Peacock and Foster Griffin to the active roster and optioning pitcher Carlos Hernández to the minors. They also placed pitcher Ronald Bolaños on the Injured List. To make room on the 40-man roster for Griffin, they transferred shortstop Adalberto Mondesi to the 60-day Injured List.
The Royals acquired Peacock from the Diamondbacks for cash considerations back on April 24. He has pitched in parts of two seasons in the big leagues, with a 4.96 ERA and 5.3 strikeouts-per-nine innings in 89 innings. The 28-year old right-hander is a sinker-slider pitcher who relies on a lot of groundballs, but doesn’t rack up many strikeouts.
