By Mets relief prospect standards, Grant Hartwig’s 2023 was a huge success in that he ended it with his elbow intact and pitched to an ERA below six. That’s a low bar to clear though, and Hartwig’s season line - 4.84 ERA, 103 DRA-, 7.82 K/9, 9.5 K-BB% in 35.1 innings - leaves a lot to be desired. His line in Syracuse wasn’t much better, making this a bit of a let down on the whole.
Hartwig entered the year with some significant momentum. A UDFA signed in 2021 whose college career was interrupted by Tommy John surgery and COVID, the right-hander impressed as he flew up the minor league ladder in 2022.
