Martin's first season with the Red Sox was possibly the finest of his career. The 37-year-old led qualified relievers with a miniscule 1.05 ERA, while his 3.82 Win Probability Added was 5th and the highest mark for a non-closer. After posting the most strikeouts of his career in 2022, Martin's strikeout rate (23.1%) dropped by nearly 10 percentage points last year, but he continued to induce plenty of grounders (51%) and rarely issued a free pass. The right-hander's 4.0% walk rate was 2nd-best among relief pitchers, as Martin continues to be one of the premiere setup men in the league. Some ratio regression is expected in 2024, but Martin's overall consistency from year to year should yield plenty of holds and the occasional ancillary save for Boston. Read Past Outlooks
