Walden signed a minor-league contract with the Cubs on Thursday.
Less than two weeks after being released by the Red Sox, Walden found a home in a new organization. The 32-year-old right-hander made 93 big-league appearances out of Boston's bullpen between 2018 and 2020, but he was unable to earn a promotion to the majors in 2021 after compiling a 4.22 ERA and 1.54 WHIP in 42.2 innings at Triple-A Worcester prior to being granted his release.
