Let's break down how the injury to Chicago Cubs starting pitcher Shota Imanaga will clear a path to the major leagues for pitching prospect Cade Horton.

Chicago Cubs southpaw Shota Imanaga left Sunday's 4-0 loss against the Milwaukee Brewers ( box score) with a strained left hamstring, marking the second consecutive start that saw him depart early with a physical issue. Last time out, Imanaga exited in the sixth inning with leg cramps.

Imanaga’s injury follows a start Tuesday in Pittsburgh in which he left in the sixth inning with leg cramps in both legs. He said he felt good Sunday before the injury, and “there was no sign in the back of my leg” before the start.
