Butler was signed out of Indy Ball back in May, but wound up recorded a lackluster 6.01 ERA, 1.64 WHIP and 55/33 K/BB ratio across 79 1/3 innings (27 appearances, 13 starts) at Triple-A Omaha. The 30-year-old righty hasn't appeared in the major leagues since 2018.

The 30-year-old has not pitched in major league baseball since 2018 but did pitch for the NC Dinos in the KBO in 2019 and the Chicago Dogs in 2020.  Butler owns a career 5.80 ERA with a 6.4 percent strikeout minus walk rate. It seems the Royals know something we don't.

The 27-year-old recently lost his spot on the Rangers' 40-man roster and was subsequently outrighted to the minor leagues. Rather than accepting a minor-league assignment and remaining a member of the Texas organization, Butler will bolt overseas for a more lucrative payday than he would have earned stateside. Depending on how well he performs in Korea, Butler could generate renewed interest from MLB teams when he becomes a free agent next winter.

Butler was removed from the 40-man roster to make room for minor-league prospects prior to the Rule 5 draft. The 27-year-old made 30 relief appearances between the Cubs and Rangers in 2018, posting a 5.62 ERA and 1.57 WHIP with 29 strikeouts over 49.2 frames.
