3. Brad Boxberger
Brad Boxberger spent the majority of the year on the 60-day injured list with a forearm strain. However, he was recently reinstated on September 8th and he's been fantastic. It is admittedly a very small sample size, but in 4.1 innings since his return, Boxberger has yet to surrender a hit or an earned run, walked one batter, and struck out four.
Yes the 35-year-old just came back from injury and he looked pretty horrible early in the year, it could be worth giving him a shot in close games. After all, he is the most experienced relief pitcher on the staff by a long shot with a career stretching back to 2012. In that time, Boxberger has collected 122 saves and 84 holds with a career ERA of 3.47. All I'm saying is it may be worth seeing if he can still lock down a game especially with so much inexperience in the bullpen right now.
