Trevor Cahill (1-3, 5.40 ERA) 

Naturally as a  starting pitcher, Trevor Cahill had an up and down 2015 campaign. With the Atlanta Braves, he pitched in 15 games going 0-3 with a 7.52 ERA. All three losses came while starting. After signing with the Cubs, Maddon made the decision to have him work out of the bullpen.

A similar move that was made with veteran southpaw, Travis Wood earlier on in the year.

In 11 games during September, Cahill began to roll with a 2.12 ERA. During the postseason, he had a 3.38 ERA in six games, becoming Joe Maddon’s right-handed setup man along the way.

Pitching coach Chris Bosio has been known to work miracles with starting pitchers that the Cubs acquire (i.e. Jake Arrieta, Jason Hammel). Bosio clearly had an impact on Cahill during his short time in Chicago during 2015, so why not bring him back?

Maybe, he can return to his 2010 form when he went 18-8 with a 2.97 ERA. If not, he can continue as the Cubs setup man. Either way, the Cubs are benefitting from his presence on the team.
