New Washington Nationals’ first baseman Josh Bell is determined to bounce back at the plate in 2021, after a down year offensively for the 28-year-old who was acquired from a rebuilding Pittsburgh Pirates club on Christmas Eve. Nationals’ GM Mike Rizzo, on Zoom after the deal, said he and his staff in the nation’s capital looked closely at Bell’s 2020 at bats and then developed a plan to help get him back to being the sort of hitter he was in 2019.
