The Boston Red Sox haven’t made many changes during the offseason. The team, following strategies mentioned by Dave Dombrowski, has remained virtually the same. The NY Yankees are on the opposite end of the spectrum. They’ve made numerous changes to their bullpen core.
The Sox lost free agent Joe Kelly in free agency to the Los Angeles Dodgers. Kelly had played an important role in middle relief. With his previous experience as a starter, he could maintain efficiency throughout numerous innings when needed. He is known to have a nasty fastball with speeds near 100mph.
