6. Joely Rodriguez
Another player who the Red Sox should close the door on is reliever Joely Rodriguez.
While he did pitch better as the campaign went on, Rodriguez still finished the year with a 6.55 ERA in 11 relief appearances. Opposing batters typically had productive at-bats when facing the Dominican hurler, tagging him for 10.6 hits and 4.9 walks per 9 innings.
Relievers are supposed to do what their name implies — bring relief to the starters — and that's something that Rodriguez struggles to do. That was made even more evident by Boston having a losing record (4-7) whenever he took the mound.
If Rodriguez was younger, I'd be fine with giving him another chance. He's turning 32 on Nov. 14, however, and likely won't get any better than what he's shown.
At the end of the day, Rodriguez is who he is at this stage of his career and the Red Sox shouldn't have a problem replacing him for a better option.
