The Cubs' new closer is Wade Davis, who was acquired in December from the Royals for Jorge Soler. Davis has experience. He helped the Royals win a World Series in 2015. In fact, the Cubs now have the three pitchers who recorded the final out in three of the last four World Series in Mike Montgomery (2016), Davis ('15) and Koji Uehara, who finished the '13 championship for the Red Sox.
This offseason, the Cubs spent most of the time thinking about how they needed to be prepared.
