Castro agreed to a one-year, $2.62 million contract with the Mets on Tuesday to avoid arbitration, Mike Puma of the New York Post reports.
Castro was a solid bullpen piece for the Mets in 2021 with a 3.45 ERA, 1.29 WHIP and 77:43 K:BB across 70.1 innings. He also recorded nine holds and could see some high-leverage opportunities if he continues to pitch well this season.
