Late in the 2021 season—less than three years ago—Grant Hartwig began his career in professional baseball. Just a few weeks before then, he wasn’t taken in Major League Baseball’s amateur draft, but the Mets signed him and sent him to Port St. Lucie.
After four appearances with their complex league squad, Hartwig got bumped up to the Single-A St. Lucie Mets for four appearances in September to end his season. In 2022, the Mets had him begin his season in St. Lucie, but he wound up playing in five different places by the time that year ended: with all four of the team’s affiliates and in the Arizona Fall League.
