Chicago Cubs: Mike Montgomery, LHP
The Cubs find themselves with a left-handed heavy starting rotation, as Montgomery inevitably rounds out the postseason group. That being said, considering the position, Montgomery does bring solid back-end production for the Cubs.
In his Cubs career, Montgomery has a 3.56 ERA over 290 innings pitched. He has been a solid starter, in his role making spot starts for the club and has established himself as a consistent producer.
This season has not been as solid for Montgomery. However, he has still pitched respectably when called upon throughout the year. He currently owns a 3.99 ERA in 121 2/3 innings pitched, with 18 starts. Montgomery has posted a 3.97 FIP and a 4.27 xFIP. In 2016, Montgomery gave up just two earned runs over ten innings pitched between the NLDS and the World Series.
While Montgomery is not the flashiest option, he does provide the necessary end of the rotation depth the Cubs so desperately need, making him the most viable option for the Cubs in the postseason.
