The Royals have designated pitcher Bruce Chen for assignment and recalled reliever Louis Coleman from Triple-A Omaha, per the team’s Twitter account.
Chen allowed six runs in an inning of work in the Royals’ 10-inning, 11-5 loss to the Twins on Thursday. The 37-year-old lefty has had a miserable season, sporting a 7.45 ERA with a 36/16 K/BB ratio in 48 1/3 innings. Chen has been with the Royals since 2009.
Coleman up and down between Triple-A and the major leagues this season. In 21 2/3 innings at the big league level, Coleman has a 7.48 ERA with a 15/13 K/BB ratio. His results at Triple-A were much better, as he carried a 3.86 ERA with a 53/15 K/BB ratio in 39 2/3 innings.
