The Chicago Cubs have a number of issues to address this offseason, one of which includes the bullpen. Cubs relievers walked 129 batters in the second half last season, which was the second-most in baseball. It is hard to point fingers at one guy because most relievers outside Wade Davis had rough patches last year.
A popular topic of conversation is Hector Rondon. The 29-year old reliever has gone from an underrated top-closer to a struggling mop-up guy in a matter of a season. His struggles last year may make people wonder if his effectiveness has been milked dry and if the Cubs should move on from him.
