Wind:

Stadium:
- Some Stadiums are more pitcher friendly then others. We rate them from Very Poor(Bad for pitcher) to Excellent(The best for pitcher). Stadium affects each Betting prop differently. It is a factor but usually not that important.
Umpire Factors:
- Each Umpire has different affect on the pitcher performance. Our table shows K Boost (Strikeout Boost), BB Boost (Walk Boost), R Boost (Runs Boost) on the pitcher performance. Umpire has big factor in Walks Allowed for example with its strikeout zone.
Umpire Factors Are Updated Every Game Day 2-3 Hours Before Match.
K Boost (Strikeout Boost)
Indicates how much an umpire tends to favor strikeouts.
A higher K Boost (e.g., 1.10x) means the umpire is more likely to call strikeouts (tight strike zone for batters).
A lower K Boost (e.g., 0.88x) means fewer strikeouts are typically called under this umpire.
🔹 BB Boost (Walk Boost)
Measures how likely an umpire is to call balls, leading to more walks (BBs).
Higher BB Boost = More generous zone = More walks.
Lower BB Boost = Tighter zone = Fewer walks.
🔹 R Boost (Runs Boost)
Reflects how many total runs are typically scored in games officiated by this umpire.
Influenced by zone tightness, consistency, and overall game pace.
Higher R Boost = More runs expected (could indicate high-scoring games).
Lower R Boost = Fewer runs expected.

B% (Walk Rate) – Opponent
Definition: Percentage of plate appearances where the opposing team’s batters draw a walk.
Higher BB% = more patient hitters who are selective and disciplined.
Effect on Pitcher:
Bad for pitchers who already struggle with control.
Can lead to more base runners and higher pitch counts.
✅ Lower is better from a pitcher’s perspective.
🔹 OPS (On-base Plus Slugging) – Opponent
Definition: Combines on-base percentage (OBP) and slugging percentage (SLG).
Higher OPS = more dangerous lineup (they get on base and hit for power).
Effect on Pitcher:
High OPS = higher chance of runs, extra-base hits, and chaos on base paths.
✅ Lower is better for pitchers (means weaker opponents).
🔹 K% (Strikeout Rate) – Opponent
Definition: Percentage of plate appearances where the opposing batters strike out.
Higher K% = more strikeout-prone team.
Effect on Pitcher:
Great for strikeout pitchers (easier outs, higher K prop potential).
✅ Higher is better for pitcher prop betting (target K Overs).
