If the Cubs are going to grab a pen arm, and at this point it is a luxury and shouldn't be a priority, it needs to be a pen arm that misses a lot of bats. They have a lot of guys who are good to great this year, but they don't have that lockdown monster who can keep guys from putting the ball in play when they need to. The Cub pen is 2nd to last in baseball in K/9 at 7.52. Right now they have 1 pen arm who exceeds 9K/9 and that's Palencia. That's super unusual.
