Rangers' left-hander Yohander Mendez was sent back to Triple-A Round Rock after violating team rules, according to general manager Jon Daniels.
Mendez, who was scheduled to start Wednesday's series finale against the Royals broke team rules away from the field. At least one other player was involved but their discipline will be handled internally, manager Jeff Banister said. Rougned Odor was scratched from Tuesday's lineup and Banister declined to say whether or not the move was related.
Right-hander Austin Bibens-Dirkx has been recalled from Round Rock and will start Wednesday.
Daniels said the violations do not involve police or major league rules and happened away from the ballpark.
