Fantasy Basketball & Baseball Waiver Brief

Produce a fantasy basketball or baseball waiver brief for standard ESPN and Yahoo leagues, basketball from October to April and baseball from March to September. Report only source-backed changes from the last 72 hours: injuries with return timelines from official reports; role, rotation, minutes and batting order changes; call-ups, demotions and trades; closer and bullpen changes; schedule density and streaming windows for the coming week; and players under 50 percent rostered with a clear reason to add, players to drop and players to stream. Prefer official injury reports, team announcements, beat reporters with team credentials, RotoWire, FantasyPros and league roster data; ignore hot takes and unverified rumors. Put the player and team first in each title and give a reason and a confidence level of high, medium or low for every call. Use high severity for a season-ending injury to a top-50 player or a closer change. Return no more than 10 findings. Push each as a finding with a title, a two-sentence summary, sections for the change, the reason, the confidence, the action, and the source link. If nothing qualifies, push nothing and submit the run receipt.
