MLB bullpen fatigue
for matchup and betting analysis.

Courtside surfaces bullpen workload as a first-class part of MLB analysis, so late-game pitching risk does not get buried behind starting pitcher stats.

How it works4 steps

From question to inspectable answer.

  1. I
    Step 1
    Pull the card

    Ask for the bullpen for one team or both.

    The card lists every reliever with role, workload score, days rest, and the per-day pitch count grid that drives the bucket.

    Example

    Show the Yankees bullpen for tonight with availability and recent usage.

  2. II
    Step 2
    Inspect the math

    Open the workload equation drawer.

    Each reliever's label is broken into the pieces that drive it: recent use, game importance, back-to-back penalty, and three-games-in-four-days risk. You can check the score instead of just trusting it.

    Example

    Why is Holmes worn and Weaver fresh when both pitched two of the last four days?

  3. III
    Step 3
    Apply to the bet

    Layer bullpen state on totals, sides, and props.

    Worn back-end bullpens raise late-inning expected runs, which matters for full-game totals, team totals, and second-half markets.

    Example

    Does Yankees' bullpen fatigue support the over here, or only after the 6th?

  4. IV
    Step 4
    Use it for DFS

    Find stacks attacking the weakest late-game pitching.

    Bullpen context shifts hitter ceilings. Stacks against a worn pen with platoon advantages get an extra check mark in the build reasoning.

    Example

    Which MLB stacks tonight benefit from the weakest late-game bullpen situation?

What it doesCapabilities

Three layers, one conversation.

01 / Why it matters

A great starter matchup can still break late.

Bullpen availability changes the shape of a baseball game. Courtside estimates reliever fatigue from recent usage and role context, then brings that table into game-outcome and totals analysis.

  • I

    Back-to-back usage and heavy recent pitch counts increase risk.

  • II

    Important late-game relievers matter more than low-pressure innings eaters.

  • III

    Team-level fatigue can change confidence on sides, totals, and late scoring.

02 / Scoring

The workload score is transparent enough to inspect.

The bullpen table is designed to show the ingredients behind the availability bucket, not just a hidden model label.

  • I

    Recency, pitch count, role, and usage concentration are separated.

  • II

    Role-based thresholds prevent every reliever from being treated equally.

  • III

    The equation drawer explains why a reliever landed in a bucket.

03 / Research use

Use bullpen context as one layer, not the whole answer.

Bullpen fatigue is most valuable when combined with starting pitching, lineup strength, park factors, weather, and market price.

  • I

    Ask how bullpen fatigue changes a full-game total versus first-five view.

  • II

    Use late-game availability to pressure-test under and team total leans.

  • III

    Pair worn bullpens with hitter contact quality and platoon advantages.

GlossaryTerms used throughout this page

A short dictionary for MLB bullpen fatigue.

01
Workload score
A simple score for how much a reliever has thrown lately. It weighs recent pitches, important game situations, back-to-back use, and three-games-in-four-days risk.
02
Availability bucket
A fresh, worn, or unavailable label based on the workload score. Closers and important late-game relievers are judged more strictly.
03
Leverage index
A measure of how important the situation was when a reliever pitched. A close late-inning spot is more taxing than low-pressure work with the same pitch count.
