Tate Southisene
Player Assessment
Current model readThe clearest reason to pay attention to Tate Southisene is the separation between what was expected and what he is currently producing. The 68 Performance Grade sits 13 points above the 55 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 assessmentSupporting Evidence
The current Baseline is 78; the model's plausible outcome window runs from 62 on the low end to 81 on the high end. The width matters: the upside is real, but the profile still has enough unresolved information to produce materially different outcomes. The supporting evidence is comparatively mature, so future movement should require a more meaningful change in performance or scouting information.
What to Watch
A promotion or sustained success against older competition is the next meaningful checkpoint. At AA, 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.
Model factors and risk context
Risk, age-to-level, track record and data quality are separate model fields. A missing value is not zero.
Projected Outcome Range
These are modeled outcome bands on the Prospect Baseline 0–100 scale, not guaranteed MLB outcomes.
Forecast
Statistical projectionsNo statistical forecast is published for this player. The current profile data does not include a documented rate forecast method, target population, or validation results.

Development Outlook
Upside and risk↑ Upside
The current Ceiling of 81 is 3 points above the Baseline. This is an outcome range, not a timed forecast.
⚑ Risk Factors
Model Risk Index: 0/100. This is a model measure, not a statement of real-world risk. Model confidence is 94/100 and is measured separately. Data quality and developmental uncertainty are also distinct.
