Red Sox Claim Chris Mazza

The Red Sox have claimed righty Chris Mazza off waivers from the Mets, as MLB.com’s Mark Feinsand first reported (via Twitter). Mazza had recently been designated for assignment.

Though Mazza is already thirty years of age and has made just nine appearances in the majors, he obviously did something to catch the eye of the Boston front office. He allowed ten earned runs with a ho-hum 11:5 K/BB ratio in his first 16 1/3 frames in the majors, hitting four of the 74 batters he faced with errant pitches along the way.

While the early showing didn’t necessarily inspire confidence, the Red Sox were surely more favorably impressed by Mazza’s work at Triple-A. Through 76 innings in the tough International League, he worked to a 3.67 ERA with 7.3 K/9, 2.1 BB/9, and a 58.0% groundball rate. Mazza has always generated a good number of worm burners. He has also long been relatively hard to take out of the park — a particularly notable statistical history in this day and age. In 2019, Mazza allowed 0.71 home runs per nine at Triple-A and didn’t surrender a single dinger in the majors.
