Ruiz will sit Thursday against Miami, Matt Weyrich of NBC Sports Washington reports.
Ruiz has handled a heavy workload behind the plate this season, as his 15 starts rank second among all catchers, trailing only J.T. Realmuto. He's made a ton of contact this season, striking out in just 9.5 percent of his plate appearances, though his overall .267/.286/.333 slash line is unimpressive. Riley Adams will take over behind the plate.
