Benoit, 40, spent last season with the Phillies and Pirates. He put up a mediocre 4.65 ERA with a 46/22 K/BB ratio across 50 1/3 innings. Only 8/13 innings came with the Pirates as he dealt with a left knee injury that kept him out of action for much of the final month and a half. He also left the team in mid-September to attend to a family matter in the Dominican Republic.
Given his age and declining performance, as well as the Nationals’ bullpen depth, Benoit doesn’t figure to pitch in many high-leverage spots, but that could change with injuries.
