MLB pitching stats & arsenals, explained
This dashboard ranks every MLB starter by the stats that matter for props — ERA, WHIP, strikeouts per nine, HR/9, plus Statcast contact-quality allowed (barrel%, hard-hit%, whiff%) — and breaks each pitcher's arsenal down pitch by pitch. HR/9 and ground-ball rate are key tells for home run and total-bases matchups.
You can filter to today's probable starters, split by pitcher handedness, and view platoon splits (performance vs left- and right-handed hitters) to find exploitable matchups. Data refreshes daily.
Which pitching stats matter most for props?
For strikeout props, look at strikeouts per nine and whiff rate. For hits, total bases, and home run props against a pitcher, weigh HR/9, hard-hit rate allowed, barrel rate allowed, and ground-ball rate — high contact quality allowed signals a vulnerable matchup.
What does a pitcher's arsenal tell you?
A pitcher's arsenal is the mix of pitch types he throws and how often. Knowing the arsenal lets you match it against how each hitter performs versus those specific pitches, which is the basis of pitch-mix matchup analysis.
What are platoon splits?
Platoon splits show how a pitcher performs against left-handed versus right-handed hitters. Many pitchers are far more vulnerable to one side, which creates clear edges when an opposing lineup is stacked with that handedness.
How often do pitching stats update?
Season stats and arsenals update nightly after games, and probable starters for the day's slate refresh each morning from the MLB Stats API.
