Cole Hamels‘ decision to sign with the Atlanta Braves officially opened up a spot in the Chicago Cubs rotation and, given the team is unlikely to spend on major pitching upgrades, it bears wondering who will fill that spot by the time Opening Day rolls around.
There appear to be a number of internal options.
Tyler Chatwood could return to the rotation after a successful stint as a long reliever in 2019. Alternatively, right-hander Alec Mills made a number of starts in September at the tail end of last season, and he showed a pretty consistent ability to log around five innings of work.
