Rodriguez signed a minor-league contract with the Nationals on Monday, Jesse Dougherty of The Washington Post reports.
Rodriguez appeared in 14 games (one start) with Washington in 2021, struggling to a 5.92 ERA and 1.73 WHIP with a 20:17 K:BB across 24.1 innings prior to being designated for assignment and ultimately outrighted to Triple-A Rochester in August. He'll get another chance with the club in 2022 but will need to earn his way back onto the big-league roster.
