EDGE Analysis

Stock was designated for assignment by the Red Sox last week, but he'll find a new spot on a 40-man roster heading into the 2021 campaign. The right-hander made 10 major-league appearances in 2020, logging a 4.73 ERA and 14:10 K:BB over 13.1 innings. Stock has an average fastball velocity of 96.8 mph, but he carries a 10.9 percent walk rate over three seasons in the majors.
