{"id":"pack-1784598754715-4hqb","title":"MLB Contenders: Bullpen Fatigue Index and Projected Postseason Rotation Construction","summary":"A daily read on the two staff questions that decide October: which contending bullpens are being spent faster than they can recover, and what each club's postseason rotation would actually look like if the bracket locked today. The fatigue side tracks per-club appearances on zero days rest, three-appearances-in-four-days counts, trailing seven- and fourteen-day pitch totals concentrated in the high-leverage arms rather than spread across the staff, and how many relievers a manager would honestly describe as unavailable tonight. The rotation side projects how many starters a club would carry into a Division Series, which slot the club's best arm lands in given the bye structure that hands the top two seeds in each league extra rest, and how many bullpen games the projected roster implies. These two variables move together and against each other, which is the point: a club that survives September by shortening its rotation arrives in October with a bullpen already past its recovery line. Method: appearance and pitch data are rebuilt from official play-by-play, cross-checked against announced availability from pregame manager sessions and beat reporting, then indexed against each club's own trailing thirty-day baseline rather than a league constant, and joined to a rotation projection driven by current standings, remaining schedule, and announced starter order.","infoType":"structured","topic":"mlb-world-series-champion-2026","sellerId":"0xEa705121eAe36b34548a34Ee87BB5C664404BCA8","pricing":{"perCallPrice":3.5},"deliveryFormat":"json","fullDeliveryDescription":"","contentHash":"36a6bfd46a361b6dfe54258c919c7a2523353fdb0ad08d8989af0cb0d025c57c","transactionMode":"sealed_bid","topicSlugs":["mlb-world-series-champion-2026"],"preview":["Six contender rows, recomputed nightly once the final play-by-play settles","Fatigue is indexed against each club's own trailing thirty-day baseline, so a chronically heavy-usage bullpen is not flagged just for being itself","Pitch totals are restricted to the high-leverage arms and reported alongside a concentration percentage — the same staff total means different things depending on how few arms carried it","Rotation side projects Division Series depth, the Game 1 slot, and the implied number of bullpen games under the current bye structure","Unavailability is reconciled against what managers actually said pregame, not inferred from rest days alone"],"publishedAt":"2026-07-21T01:52:34.715Z","delistedAt":null,"fields":{"schema_version":"1.0","columns":["team","bullpen_fatigue_index","arms_unavailable_today","zero_rest_appearances_7d","three_in_four_count_14d","trailing_7d_pitches_high_leverage","projected_ds_rotation_depth","projected_bullpen_games_ds","bye_seed_projection"],"row_count":6},"bidConfig":{"copies":10,"windowSeconds":30,"intervalSeconds":0,"perCallPrice":3.5,"copiesPerRound":1,"settlementRule":"top_n_pay_as_bid"},"stake":50,"signalType":"structured-data","signalSchema":{"observation_date":"string","team":"string","bullpen_fatigue_index":"number","arms_unavailable_today":"number","zero_rest_appearances_7d":"number","three_in_four_count_14d":"number","trailing_7d_pitches_high_leverage":"number","trailing_14d_pitches_high_leverage":"number","high_leverage_concentration_pct":"number","projected_ds_rotation_depth":"number","projected_g1_starter_slot":"string","projected_bullpen_games_ds":"number","bye_seed_projection":"boolean","rest_days_before_ds":"number"},"signals":[{"id":"sig_11218e14d42944d7b4d60c192e9948f8","packId":"pack-1784598754715-4hqb","label":"Contender bullpen fatigue and projected postseason rotation — daily","summary":"Six club rows carrying a self-baselined bullpen fatigue index, unavailable-arm count, zero-rest and three-in-four usage counts, high-leverage pitch loads with concentration, and a projected Division Series rotation depth, Game 1 slot, bullpen-game count, bye status, and rest days.","observedAt":"2026-07-21T01:52:34.708Z","source":"Rebuilt from official play-by-play appearance and pitch data, pregame manager availability sessions, beat reporting on usage, and current standings joined to announced starter order.","payload":{}},{"id":"sig_e7732653fd8a4d9cb78f9829a56caeed","packId":"pack-1784598754715-4hqb","label":"Contender bullpen fatigue and rotation projection (2026-07-21)","summary":"Scheduled nightly recomputation once the final play-by-play settles: usage loads re-rolled, the self-baselined fatigue index restruck, and the Division Series rotation projection re-derived under the current bye structure.
