Baez long term in Boston is asking for trouble. In his eight-year career, the guy has struck out 29.3% of the time. That's more than Schwarber, JD, Renfroe, Devers -- every regular in last October's starting lineup. In addition, playing in a new league facing and learning new pitchers can be a struggle initially (ask JBJ, a career 25.9% whiffer).
Imagine Baez having issues adjusting, fanning continually in big spots, and hearing boos -- will he react the way he did for the Mets? Red Sox fans won't be so forgiving, especially if he's owed nine figures.
