The offseason of 2016 saw the Chicago Cubs make one of the more under-the-radar moves in bringing in left-handed relief pitcher Brian Duensing. The deal itself was excellent. A one-year deal worth just $2 million, giving the club a low-risk investment with potential upside out of the bullpen.
It manifested into just that, as Duensing finished his 2017 campaign with a very respectable 2.74 ERA in 62 1/3 innings. Duensing rode the success of the regular season into the postseason as well, allowing just one earned run in 5 1/3 innings pitched. Not a significant sample size, but regardless he displayed consistency.
