| Summary: A switch pitcher is always fascinating, but Cijntje isn’t just an oddity and the real value shows most clearly from the right side, where the delivery, stuff, and strike-throwing all take a step forward. From a low release, the fastball works into the mid-90s with carry through the zone, creating uncomfortable angles for hitters, and the cutter-ish slider is the separator — firm, late, and thrown with confidence as his primary bat-miss pitch. He’ll also flash a developing curveball with depth and a changeup that shows enough fade to hint at a starter’s mix when the feel is right. As a right-hander, the operation looks repeatable, athletic, and far more consistent than the novelty label might suggest. The long-term question is less about ability and more about focus. The left-handed look plays more like a situational change of pace, with softer shapes and a relief-leaning profile, while the right-handed version carries legitimate starter traits. If the development path continues to prioritize the right side, the fastball/slider foundation gives him a chance to hold rotation value, with the changeup determining how often he can turn a lineup over. Durability questions are tied more to frame than effort, and the upside ultimately hinges on whether simplifying the role allows the stuff to fully stabilize. | |||||||||||
