​Following the developmental path of Detroit Tigers’ starting pitcher Troy Melton has been a pretty fascinating ride. Watching him improve in 2024, it was pretty clear that he would become a factor in 2025 if he could avoid the plague of pitcher injuries in the Tigers’ system, and so it went. However, during his mixed work as a starter and reliever down the stretch and in the postseason, his ability to handle left-handed hitters was the question determining his long-term future as a starting pitcher. This year, the 25-year-old Melton has found the answer, but it’s not the pitch we were expecting.Last fall, I wrote about Melton’s splitter being the defining factor in locking down left-handed hitters, and argued that the cutter either had to get a lot better or be ditched entirely. Melton has chosen the first of those paths. He was good overall in his rookie season, and pitched pretty impressively in the postseason as well. Left-handers weren’t a huge problem for him, but they hit him quite a bit better than right-handers, and more specifically, Melton struggled to strike out left-handed hitters.AdvertisementAdvertisementAdvertisementHe managed a meager 14.2 percent K-rate against lefties in 2025. He struck out 26.2 percent of right-handed hitters. That was all fine in a relief role, but to really become a dominant starting pitcher, he was going to have to get a lot more whiffs against left-handed batters in particular. The .191 BABIP he ran against lefties just wasn’t going to hold up, especially as a full-time starter.The answer, I assumed, lie in his split-finger fastball. Typically the development of a changeup or splitter is the key to limiting damage and getting whiffs against opposite handed hitters. Melton’s fourseam-slider combo wasn’t really going to get it done. Melton has gone another direction, turning his cutter into a monster weapon against hitters on either side of the plate.In 2025, Melton threw the cutter just 10.8 percent of the time, regardless of which batter’s box the hitter was in. In 2026, that rate is up to 20.1 percent.Against lefties, he uses the cutter 19.5 percent of the time. He’ll mix in the splitter (12.1%)and curveball (8.1%) sparingly against them, accounting for about 20 percent of his pitches to lefties combined. The slider is used 18.3 percent of the time against lefties, while the majority of the work is still handled by his fourseam fastball, which he throws 40.8 percent of the time.AdvertisementAdvertisementAdvertisementSo he’s still using a pretty deep mix against left-handed hitters, but the cutter is certainly playing a lot bigger role than it did in 2025. It’s also suddenly become a much better pitch in recent weeks. In 2025 he averaged 90.9 mph with it. He’s added a full tick of velo this season, but lately he’s really found the feel with it and is throwing it even harder, even topping 95 mph repeatedly in late June and July. Since June 15, the cutter is averaging 92.5 mph. The
