Seth Martinez News: Signs with Red Sox as NRI

Published on January 9, 2026

The Red Sox signed Martinez to a minor-league contract Friday that includes an invitation to spring training, Andrew Parker of SoxProspects.com reports.

Martinez has produced a 4.00 ERA and 126:57 K:BB over 144 innings covering parts of five major-league seasons. The 31-year-old will try to win a spot in the Boston bullpen but is likely ticketed for Triple-A Worcester to begin the 2026 campaign.
