The Guardians have acquired left-hander Foster Griffin from the Nationals, as first reported by MLB.com’s Mark Feinsand. The breakout carried over to the majors, as Griffin basically replicated that performance over 22 starts for the Nationals. While his walk rate is elite, Griffin’s under-the-hood numbers are mostly average, and he has benefited from a .256 BABIP. The Guardians’ solid rotation only gets stronger with Griffin in the mix. From Washington’s perspective, obtaining four players is a very nice coda on the investment in Griffin.
