Prospect Baseline Rank #164

Player Assessment

Current model read

Performance is doing more work than the scouting grade in Sebastian Dos Santos's current evaluation. The 65 Performance Grade sits 20 points above the 45 scouting foundation, a large enough gap to change the shape of the evaluation. The age-to-level relationship adds development value to the current performance.

Supporting Evidence and What to Watch

Current model assessment

Supporting Evidence

The current Baseline is 71; the model's plausible outcome window runs from 65 on the low end to 74 on the high end. The narrow spread suggests the profile is becoming more settled rather than being driven by one volatile signal. The supporting evidence is comparatively mature, so future movement should require a more meaningful change in performance or scouting information.

What to Watch

The development advantage is already being rewarded, so the next question is how well the skills travel upward. At Single-A, age-to-level context is already helping the projection. Maintaining the same indicators against stronger competition would strengthen the Baseline more than simply repeating the current line in place.

Development Outlook

Upside and risk

↑ Upside

The current Ceiling of 74 is 3 points above the Baseline. This is an outcome range, not a timed forecast.

⚑ Risk Factors

Model Risk Index: 3/100. This is a model measure, not a statement of real-world risk. Model confidence is 89/100 and is measured separately. Data quality and developmental uncertainty are also distinct.
