A look at how the bullpen shapes up after the addition of Edward Mujica:
RHP Koji Uehara: Counting the playoffs, he appeared in 86 games last season. Breaks could be needed.
RHP Junichi Tazawa: Struck out 72 and walked 12 in 68⅓ innings. With confidence, he’s a future closer.
LHP Craig Breslow: A workhorse down the stretch and in the postseason.
RHP Edward Mujica: Saved 37 games for the Cardinals last season. Profiles as Uehara’s backup.
LHP Andrew Miller: Broken foot in July ended the best season of his career.
RHP Brandon Workman: Rookie quickly earned trust as a reliever. But his future could be in the rotation.
Fighting for a job
LHP Franklin Morales: Injuries limited him in 2013. But his fastball is too lively to ignore.
RHP Burke Badenhop: Acquired from Milwaukee last month. Red Sox like his groundball rate.
LHP Drake Britton: Rookie showed fortitude last season after starting in the minors.
RHP Alex Wilson: A thumb injury kept him out of the majors for the final three months.
RHP Rubby De La Rosa: He turns 25 in March. Clock is ticking for a talented pitcher. Is he a starter or reliever?
RHP Brayan Villarreal: Obtained in the Jake Peavy/Jose Iglesias trade, he appeared in only one game and walked in the running run.
RHP Steven Wright: Knuckleballer could be long reliever. Faces rotation squeeze in Triple A.
RHP Chris Martin: Independent league find opened eyes in Triple A.
