Last week the Red Sox made a bit of a surprising move when they designated Chris Mazza for assignment to make room on the 40-man roster for the addition of Martín Pérez. Mazza was by no means great in 2020, but he was a solid bit of rotation depth who figured to play an up-and-down role in 2021. Well, that move makes a little more sense now as they were able to flip the righty, along with Jeffrey Springs, who was DFA’d on Tuesday, to a division rival for a pair of minor leaguers. According to Alex Speier, Boston has sent the two pitchers to the Rays in exchange for two prospects, including catcher Ronaldo Hernández.
