The departures of Jon Lester and Jose Quintana to free agency left the Cubs with no lefthanders in their rotation when the 2021 season began, and it took until Game 114 of this past season until a lefty (Justin Steele) started a game for the Cubs. Steele was the only lefthander who started any games for the Cubs in 2021, nine in all.
So as the Cubs look to upgrade their rotation for 2022, a lefthander or two would be quite useful.
Some have suggested the Cubs look at Blue Jays lefthander Robbie Ray, but he’ll be expensive.
