Closer: Koji Uehara
The 39 year-old Uehara re-signed with Boston on what will likely be the last deal of his career, a two year $18 million deal. If the Red Sox get 2013 and pre-ASB 2014 Uehara then this signing will be great for the team. But if we continue to see him pitch the way he did down the stretch in 2014 this contract will look really bad, but more importantly, the bullpen may be in serious trouble. A lot will be riding on his performance.
Set-Up Man: Junichi Tazawa
There were some murmurs, that Taz was looking for a chance to either close or start. Assuming there is nothing to these rumors, he will remain where he is best suited, as a terrific 8th inning pitcher. The 28-year-old has been great for the team and should continue that success as he enters his prime years.
RHP: Anthony Varvaro
Acquired from the Braves in December as an unheralded but talented name, Varvaro is another right handed weapon for manager John Farrell to utilize in late innings. The 30-year-old had a 2.63 ERA with an 8.2 K/9 and 49.7% groundball rate in 2014.
LHP: Robbie Ross Jr.
One of the more recent additions to the team, Ross was sent to Boston from the Rangers for pitching prospect Anthony Ranaudo. The 25 year-old Ross struggled after being moved to the rotation in 2014, but was a good southpaw reliever in 2012-2013.
RHP: Edward Mujica
A possible trade candidate, it looks for now as though Mujica will play out the remaining year on his two year deal with Boston. Mujica came alive down the stretch as Uehara faltered but on the season his ERA was 3.90.
LHP: Craig Breslow
This was a surprising re-sign in my mind. Breslow was a high character guy, but had a really rough 2014. The team will be counting on a bounce back from him as well.
Swingman: Alexi Ogando
Possibly the most talented pitcher in the bullpen, Ogando was electric as both a starter and a reliever from 2010-2013. He dealt with numerous injuries in 2014, but should he prove healthy, will likely make the team.
