Duffey agreed to a one-year, $3.8 million contract with the Twins on Tuesday to avoid arbitration, Aaron Gleeman of The Athletic reports.
Duffey recorded a 3.18 ERA, 1.22 WHIP and 61:28 K:BB over 62.1 innings while recording three saves and 22 holds last season. He should enter spring training as a high-leverage bullpen option for Minnesota next year.
