| Summary: The arm strength is extreme, even by pro standards, and Susana operates with a level of raw velocity that immediately separates him from most pitching prospects. He works comfortably in the upper-90s and routinely reaches triple digits deep into outings, showing both four-seam and two-seam variations that overwhelm hitters on sheer power alone. The velocity comes without obvious max effort, but release consistency and fastball shape still fluctuate, causing the heater to play more as a pure velo weapon than a true deception pitch at times. The delivery sat in a lower three-quarters slot with some east-west misses, reinforcing lingering command concerns and a reliever-leaning visual despite starter traits. The slider is the defining secondary and a legitimate bat-misser at the highest level. He can manipulate shape, flashing a harder, tighter version with vertical bite as well as a sweepier look that expands the zone laterally. The harder slider tunnels especially well off the fastball and consistently generates chases and empty swings when he sequences it properly. This fastball/slider combination alone is good enough to dominate in shorter stints, and it showed clearly in high-octane looks where hitters were overmatched even when they knew velocity was coming. The developmental hinge remains the changeup and overall strike efficiency. He has experimented with multiple grips but feel and usage lag well behind the primary two pitches, allowing opposite-handed hitters to sit hard. Delivery improvements have helped him throw more competitive strikes, but command still projects closer to average than a true strength, with misses tending to leak when his timing gets rushed. Health history adds volatility, yet when everything lines up, the combination of elite velocity, a true plus-plus slider, and improving control supports a high-impact rotation outcome — with a late-inning power reliever fallback if durability or command ultimately cap the role. | |||||||||||
