The Red Sox have designated right-hander Chris Mazza for assignment, per Chris Cotillo of MassLive.com. They did so in order to make room for the re-signing of lefty Martin Perez.
Mazza joined the Red Sox in late 2019 as a waiver claim from the Mets, and he became a regular in Boston’s staff last season. The 31-year-old finished fifth among Red Sox pitchers in innings (30), though he was unable to establish himself during that time. Mazza posted a 4.80 ERA/4.97 SIERA with subpar strikeout (21.3) and walk (11.0) percentages. He does, however, have another option left and a good track record in the minors, where he has pitched to a 3.21 ERA in 507 2/3 frames.
