The Mets have agreed to minor league contracts with pitchers Robert Stock, Nick Burdi and Anderson Severino and with outfielder Jose Ramos, according to SNY. Mike Rodriguez reported the Severino agreement a couple weeks ago, while Burdi’s deal first appeared on the MLB.com transaction log. Stock has confirmed his signing on social media. All four players receive invitations to big league camp.
Burdi and Stock each spent the 2025 season in the Red Sox organization. They both got brief looks in Alex Cora’s bullpen. Burdi tossed 5 1/3 scoreless innings with five strikeouts and a pair of walks over four appearances. The 32-year-old has good stuff but has never been able to stay healthy. He missed a couple months with a foot injury this year and has previously had thoracic outlet syndrome, two Tommy John surgeries, appendicitis, and hip issues. Burdi has a career 3.05 ERA with a 31.3% strikeout rate in 76 2/3 Triple-A innings. He has pitched in parts of six MLB campaigns but has yet to reach even 10 big league innings in a season because of the injuries.
Stock, 36, made two appearances for the Sox this year. He walked four batters and gave up three runs over 2 2/3 innings. Stock has worked as a reliever in MLB but started 15 of 19 outings at Triple-A Worcester. He tossed 85 innings with a 3.92 ERA while punching out an above-average 26.2% of batters faced. Stock hasn’t found much MLB success since turning in a 2.50 ERA over 32 appearances as a rookie with the 2018 Padres. He still sits in the mid-90s with his fastball and has intrigued various teams as a depth signing. Stock previously spent time in the Mets’ system, starting four Triple-A games for the organization in 2021.
Severino is a 31-year-old lefty reliever who pitched six times for the White Sox in 2022. He has spent the past two seasons pitching in the Mexican League. Severino has tossed eight innings of two-run ball with 11 punchouts in the Dominican Winter League to get back to affiliated ball. Ramos, 25 in January, has never played in the majors. He spent seven seasons in the Dodgers’ system and combined for a .251/.326/.456 batting line between their top two minor league affiliates in 2025. The right-handed hitter changes organizations for the first time as a minor league free agent.
