Pitching Charts
Top Pitchers by RA
Shows the top 10 pitchers with the lowest RA (Run Average — runs allowed per 9 innings). Lower RA means a more effective pitcher. WHIP (Walks + Hits per Inning Pitched) measures how many baserunners a pitcher allows.
Team Pitching Comparison
Compares teams by three pitching metrics: RA (Run Average — lower is better), WHIP (Walks + Hits per Inning — lower is better), and K/9 (Strikeouts per 9 innings — higher is better).
Pitch Outcomes
Shows the distribution of all plate appearance results faced by pitchers: Strikeouts, Walks, Hits, and Other Outs. A higher strikeout percentage and lower walk/hit percentage indicates better pitching.
Pitcher Workload
Each bubble represents a pitcher. The horizontal axis shows innings pitched (IP) and the vertical axis shows strikeouts per 9 innings (K/9). Pitchers in the top-right are high-volume strikeout pitchers. Bubble size reflects batters faced.
K/BB Rate
Each bubble represents a pitcher. The horizontal axis shows strikeout rate (K%) and the vertical axis shows walk rate (BB%). Pitchers in the bottom-right have the best command — high strikeouts, low walks. Bubble size reflects batters faced.
RA by Inning
Tracks the Run Average (runs allowed per 9 innings equivalent) across each inning. A rising line suggests pitchers tend to tire in later innings.
ERA+ vs K% (Hot & Cold)
Each dot is a pitcher, plotted by strikeout rate (K%, horizontal) and ERA+ (vertical — runs prevented vs. the league average, where 100 is average). The red dotted line marks league-average ERA+ (100); the green dotted line marks the K% average for the current filter. Dots are colored by quadrant: bright red = elite (high K%, high ERA+), orange = contact survivors, teal = unlucky power arms, deep blue = underperforming.
