When you're diving into player stats on Outlier, you may notice that some numbers are highlighted in green or red.
This color-coding is designed to help you quickly identify whether a player is overperforming or underperforming in specific splits compared to their overall season averages.
What do the colors mean?
✅ Green: The stat is higher than the player’s season average. This means the player is performing better in this specific split.
❌ Red: The stat is lower than the player’s season average. This indicates the player is performing worse in this specific split.
Example: vs. Right-Handed Pitching (RHP)
In the image below, you're looking at Cleveland hitters’ performance against right-handed pitchers in 2025:
Take José Ramírez for example:
His batting average vs. RHP is .299 — this number appears in red.
That’s because his overall average this season is .350, meaning he’s underperforming in this split compared to his norm.
Now look at Steven Kwan:
His .319 average vs. RHP is shown in green.
Why? Because it's higher than his overall season average, so he’s thriving against righties.
Why this matters
These color cues are super useful for spotting trends and mismatches. If you’re trying to evaluate a prop or lineup spot, seeing a red stat might indicate caution, while a green one could signal a hot hand in a favorable matchup
Understanding Red vs. Green Stats for Pitchers
Pitchers also include split stats based on the handedness of the opposing batter. These splits help you understand whether a pitcher has performed better or worse against left-handed or right-handed hitters compared to their overall season performance. Handedness is an important factor in baseball, as many pitchers and hitters perform differently depending on whether they're facing an opponent of the same or opposite hand.
For example, in the screenshot below, Nathan Eovaldi is facing Austin Riley, a right-handed batter.
The 2026 row shows Eovaldi's overall season statistics.
The vs. RHB row shows how he has performed specifically against right-handed batters.
Reading the colors
Just like hitter splits:
Green indicates the pitcher has performed better in that statistic compared to their overall season numbers which makes the matchup more favorable.
Red indicates the pitcher has performed worse than their season average for that statistic and makes the matchup less favorable.
In this example:
ERA: Overall 4.04 → 3.86 vs. RHB (green), meaning Eovaldi has allowed fewer earned runs against right-handed hitters.
BAA (Batting Average Against): Overall .245 → .221 vs. RHB (green), meaning right-handed hitters are batting a lower average against him.
SLG (Slugging Percentage Against): Overall .423 → .368 vs. RHB (green), meaning he's allowing less power against right-handed hitters.
Taken together, these green values suggest Eovaldi has been more effective against right-handed batters than he has been overall this season.
Note: Split stats are intended to provide additional context and should be considered alongside other information such as recent performance, historical batter vs. pitcher results, weather, ballpark factors, and pitch arsenal—not as a standalone indicator of how a player or pitcher will perform in a given game.
