The Nationals signed starting pitcher Jon Lester to a one-year contract on Monday, according to ESPN's Jeff Passan.
Washington and Lester will have a mutual option for the 2022 season, per Passan.
Lester, 37, posted a career-worst 5.16 ERA in 12 starts in 2020. But he could bounce back in 2021 as a valuable depth piece for Washington behind top starters Max Scherzer and Patrick Corbin. Lester has tallied 193 wins in 423 career starts, sporting a 3.60 career ERA. He previously spent the last six seasons with the Cubs after nine years in Boston.
