Chatwood posted an 8-15 mark and a 4.69 ERA in 33 appearances last season for the Colorado Rockies.
The Cubs could potentially lose right-hander Jake Arrieta as a free agent this offseason, so signing Chatwood gives Chicago another bona fide starter.
Chatwood has had stark home-road splits while calling hitter-friendly Coors Field his home. His curveball spin rate, a skill teams are seeking out these days, was among the best in baseball the last two years. On the road, he recorded a 3.49 ERA and held foes to a.200 batting average. But when you look at his numbers away from Coors Field, he's not too much of a step down.
Tyler Chatwood is getting a fresh start in the Windy City. Across the 2016 and 2017 seasons, Chatwood has a 2.57 ERA on the road, which tied for the second-best mark in the National League for those with a minimum of 10 starts. Since returning from his second career Tommy John surgery in 2016, he threw 305 2/3 innings with a 4.27 ERA (115 ERA+) for the Rockies. For his career, which included his first season with the Angels, Chatwood is 40-46 with a 4.31 ERA. Chicago also is waiting to see if Japanese two-way player Shohei Ohtani picks the Cubs, who are one of the seven finalists.
