Korean free agent pitcher Go Woo-suk is nearing a new minor league deal in the United States after being released last week, sources close to the pitcher said Tuesday. According to the sources, the right-hander is close to signing a deal with the Toledo Mud Hens, the Triple-A affiliate of the Detroit Tigers.
