BatterUp Fantasy

About this app

Batter Up Fantasy is the fastest way to know what your fantasy MLB players are doing — without compulsively refreshing three different apps. CONNECT YOUR LEAGUES Sign in once with Yahoo, ESPN, Fantrax and/or CBS Sports. Mix and match — every team you manage on every platform shows up in a single feed. NOTIFICATIONS THAT MATTER - Lineup posted: instant push the moment your hitter is in (or out of) today's starting lineup, with batting order - Sitting today: separate toggle so you know who's NOT playing - Pitcher starting: heads-up when your starting pitcher is on the bump - Live scoring: hits, home runs, and stolen bases as they happen - On-deck and in-the-hole: never miss a key at-bat - Per-team toggles: mute the alerts from teams you've already decided about TODAY VIEW Every player on every roster, grouped by lineup status. A "N leagues" badge tells you when one player is helping you in multiple matchups. NO ADS. NO TRACKING. WE NEVER SEE YOUR PASSWORD — Yahoo OAuth and in-app sign-in for ESPN, Fantrax and CBS Sports mean your credentials go straight to the provider. Not affiliated with Yahoo, ESPN, Fantrax, CBS Sports, MLB, or any team. Fantasy data is read-only.

Yahoo Fantasy sign-in has been refreshed to keep working with recent Yahoo account changes. Yahoo users: after updating, please tap Settings → Connected Accounts → Disconnect Yahoo, then Connect Yahoo again to restore your teams. One-time re-login only. Improved player recognition — nearly every rostered MLB player now correctly resolves to their MLB headshot and per-player game history. Small polish fixes throughout. ESPN, Fantrax, and CBS Sports users: no action needed.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
