The Giants have designated right-handed Vin Mazzaro for assignment, as Alex Pavlovic of CSN Bay Area tweets. He’ll be replaced on the roster by fellow righty Albert Suarez, whose contract was purchased from Triple-A.
Mazarro, 29, only made two appearances for San Francisco, but the second was something to remember — for all the wrong reasons. He surrendered six hits, a walk, and seven runs while retiring just one batter.
Of course, there have been better days in the past. In his best year, Mazzaro put up 73 2/3 frames of 2.81 ERA ball for the Pirates back in 2013. That was the only season in which he’s walked less than three batters per nine and carried a groundball rate over 50%.
