The Cubs signed left-hander Hong-Chih Kuo to a minor league deal, Paul Sullivan of the Chicago Tribune reports (on Twitter). Kuo signed a Major League deal with the Mariners in February and has been a free agent since Seattle released him in March.
Kuo struggled through 40 appearances in 2011, posting a 9.00 ERA with 12.0 K/9 and 7.7 BB/9 and missing time with an anxiety disorder. His results were much better before last year; he had a 3.19 career ERA with 10.5 K/9 and 3.5 BB/9 entering the 2011 season. The 30-year-old Octagon client underwent his fifth career elbow surgery in October of 2011 and the Dodgers non-tendered him two months later.
