The Red Sox have claimed right-hander Robert Stock off waivers from the Phillies, as per a team press release. Philadelphia designed Stock for assignment earlier this week.
Stock represents the latest new arm in Boston’s organization, as the Sox have also added the likes of Zack Godley, Dylan Covey, and Stephen Gonsalves in recent days in an attempt to shore up a pitching staff thinned by injuries, COVID-related absences (i.e. Eduardo Rodriguez) and opt-outs (Collin McHugh). The Red Sox have optioned Stock to their minor league training site, though it isn’t hard to imagine him getting a call to the MLB roster at some point, as the Sox continue to figure out their optimal bullpen mix.
The hard-throwing Stock has a 4.11 ERA over 50 1/3 career innings, all as a reliever, and all with the Padres from 2018-19. After posting a 2.50 ERA in 39 2/3 frames in 2018, Stock struggled to a 10.13 ERA over 10 2/3 innings last season as his walk rate and homer rate both ballooned, and he also hit the injured list with a biceps strain in September.
Stock was a second-round pick for the Cardinals in the 2009 draft, though he pitched for a few different organizations (as well as stints in Mexico and independent baseball) before finally reaching the Show in 2018. The 30-year-old has a 3.74 ERA, 1.54 K/BB rate, and 8.5 K/9 over 327 career minor league innings, working as a reliever in 210 of his 217 appearances.
