4. 3B Edwin Rios
One of the many third basemen that the Cubs have in the Triple-A and MLB levels is Edwin Rios. The Cubs brought Rios aboard on a one-year deal worth $1 million in February and it looked like he was vying for a role. But Manager David Ross rarely gave Rios a plate appearance, let alone a start. He only collected 28 at-bats in 34 games with a .071/.235/.214 slash line. He was eventually removed from the 40-man and outrighted to the Iowa Cubs in July.
Rios has shown glimpses of greatness but has never really been given a proper chance to play every day. Before his time with the Cubs, Rios came up with the Los Angeles Dodgers, where he played just 112 games over four years. The 29-year-old would get a better chance to showcase his skills on a non-competitive team like the Oakland Athletics or the Kansas City Royals. Hopefully, he can find his way to a team like that and get prove himself.
