Japanese left-hander Shota Imanaga and the Chicago Cubs are working toward an agreement, a source told ESPN's Jesse Rogers on Tuesday.

Imanaga, 30, excelled during eight seasons with the Yokohama Bay Stars in the Nippon Professional Baseball Organization, going 74-55 with a 2.96 ERA and striking out 1,183 in 1,129⅔ innings.

He throws a variety of pitches — in addition to the fastball, he's got a splitter, a traditional slider, a sweeper, a curveball, a cutter and a straight changeup — though he could lessen his arsenal as he transitions to a different ball in MLB as well as more frequent starts.

Imanaga would fit near the top of the Cubs' rotation behind ace Justin Steele. Jameson Taillon and Kyle Hendricks slot in next, with youngsters Jordan Wicks and Javier Assad in the mix at the back end.

The move would easily be the Cubs' largest of the winter, as they were only showing up on the transactions page via minor league signings, outside of backup catcher Brian Serven, who they
