| Summary: There’s a lot to like in Sloan’s foundation, starting with a power starter’s build paired with a delivery that allows the ball to get on hitters quickly. He works from a three-quarters slot with good extension and angle, creating a flat approach that helps the fastball play above the radar reading. The heater generally lives in the mid-90s and has reached the upper-90s, with the ability to manipulate shape—showing ride when elevated, sink when he stays through it, and occasional cut. He attacks the zone with confidence and shows an advanced feel for sequencing, traits that separate him from most prep power arms. The secondary mix is already functional and trending upward. The changeup stands out as a legitimate weapon, showing late dip and run in the mid-80s and flashing the confidence to be used early in counts, even against quality hitters. The slider sits in the low-80s and can show sharp, late break with both vertical and sweepy looks, though consistency still comes and goes. When he stays on top of it, it has bat-missing potential; when he doesn’t, it can back up and blur with cutter shape. There’s enough feel to spin and shape the baseball to project multiple above-average offerings long term. Strike throwing and delivery repeatability give the profile real stability. He’s comfortable working backward, shows poise for his age, and generally fills the zone rather than nibbling, with misses more tied to timing lapses than a lack of control. Seattle has managed the workload carefully, but the combination of size, stuff, and mound presence points toward a true starter track. If the slider tightens and the fastball shapes continue to separate more clearly, there’s a realistic path to a rotation piece with impact upside rather than just velocity-driven projection. | |||||||||||
