The Red Sox announced that they’ve designated catcher Oscar Hernandez for assignment in order to open a spot on the 40-man roster for right-hander Trevor Kelley, whose previously reported promotion is now official. Right-hander Mike Shawaryn was optioned to Triple-A to open a spot on the 25-man roster.
Hernandez, 25, was with the Red Sox earlier this season when Sandy Leon was on paternity leave, but he didn’t get into a game during his brief call to the Majors. He hasn’t appeared in the big league since 2016 with the Diamondbacks, who took him with the top pick in the 2014 Rule 5 Draft. Hernandez saw only minimal time with the D-backs over the next two seasons and hit .167/.239/.262 in a tiny sample of 47 plate appearances in the big leagues.
A defensive-minded catcher, Hernandez has regularly posted solid framing numbers in his minor league career and has thrown out 41 percent of potential base thieves. Solid as he is behind the plate, he’s not much of a threat in the batter’s box. Hernandez carries a paltry .190/.240/.344 batting line in 431 Double-A plate appearances and just a .204/.273/.286 slash through 277 career trips to the plate in Triple-A. Boston will have a week trade Hernandez, release him or attempt to pass him through outright waivers.
