Luke Gregerson, RP
The bullpen hasn’t been a major area of need even in a rough 2014 season, but after trading Andrew Miller at the Trade Deadline, the Red Sox could still look to revamp their ‘pen in the offseason. Gregerson is an elite setup man and has had a great year in his first season with the Oakland Athletics, posting a 2.26 ERA and 3.83 K/BB in 55 appearances. Gregerson, along with Junichi Tazawa, would give the Red Sox two top-notch setup men as they look to contend.
The Red Sox don’t have much money committed towards the future; thus, they could easily afford a contract in the range of a 3 year/$20M deal. That’s big money for a non-closer relief pitcher but Gregerson is as deserving as they come. The highest ERA that he has ever posted is 3.24 in his rookie season and, aside from an outlying 2013 season in which he had a 2.71 ERA (terrible, right?), his ERA has lowered every season of his Major League career. At 30 years old, he should stay effective for several more years, and the Red Sox would be right to let him continue his success in Boston.
