The Minnesota Twins are making a bold move in their bullpen strategy, signing right-handed pitcher Grant Hartwig to a minor league deal—but is this a smart gamble or a missed opportunity? Here’s the scoop: According to Darren Wolfson of KSTP, the Twins are bringing Hartwig into the fold, complete with an invite to major league spring training. But here’s where it gets controversial: Hartwig, who turns 28 this month, has a limited and somewhat underwhelming MLB track record. In 42 innings with the Mets across the 2023 and 2024 seasons, he posted a 5.14 ERA, striking out just 18% of batters while walking 10.1%. Not exactly eye-popping numbers, right? Yet, there’s more to the story.
Hartwig’s journey took an unexpected turn in 2025 when he headed to Japan to play for the Hanshin Tigers. In a small sample of 12 1/3 innings, he delivered a respectable 3.65 ERA. But here’s the part most people miss: His strikeout rate dipped to 15.1%, and his walk rate climbed to 13.2%. So, what does this mean for the Twins? And this is the part most people miss: Hartwig’s minor league numbers are a mixed bag. Since 2023, he’s logged 94 2/3 innings, mostly at Triple-A, with a 4.47 ERA, a solid 25.6% strikeout rate, but a concerning 11.3% walk rate. In 2025, he showed promise with a 3.42 ERA and a 29.2% strikeout rate in 23 2/3 innings, but can he sustain that at the major league level?
The Twins’ bullpen overhaul last year left them with a glaring need for fresh arms, but is Hartwig the answer? After trading away key relievers like Jhoan Duran, Griffin Jax, and Louis Varland, the team’s 2026 plans remain unclear. Are they rebuilding, or are they aiming to compete? Either way, Hartwig’s roster flexibility—he’s still optionable with less than a year of service time—makes him an intriguing low-risk, high-reward option. But let’s not forget: his control issues and inconsistent performance could be a red flag.
Here’s the burning question: Can Grant Hartwig turn his minor league potential into major league success, or will he be just another footnote in the Twins’ bullpen experiment? What do you think? Is this a smart signing, or should the Twins have looked elsewhere? Let’s debate it in the comments!
