Reliever Grant Hartwig has signed with the Hanshin Tigers of Japan’s Nippon Professional Baseball. The 6’5″ righty had been on a minor league contract with the Mets but was released last month. It seems that was to pursue this opportunity.
Hartwig, 27, pitched in the big leagues for the Mets in each of the previous two seasons. He logged 35 1/3 innings of 4.84 ERA ball as a rookie in 2023. He spent most of last year in Triple-A and lost a couple months to a meniscus tear that required surgery. Hartwig appeared in four MLB games, allowing six runs in 6 2/3 innings. The Mets dropped him from the 40-man roster early in the offseason and brought him back on a minor league deal.
A product of Miami Ohio, Hartwig signed with the Mets in 2021 as an undrafted free agent. He has turned in a 3.42 earned run average in parts of five minor league campaigns. Hartwig had a matching 3.42 ERA across 23 2/3 Triple-A frames this year, though he bizarrely surrendering 13 unearned runs (against nine earned) in 21 appearances. He fanned 29% of batters faced with a solid 8.8% walk rate while averaging nearly 95 MPH on his sinker. Hartwig will presumably lock in a stronger guarantee in NPB than he would’ve made had he played out the season in Triple-A.
