Never Miss an At-Bat Again!
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.
CBS Sports Fantasy is here! Connect your CBS league from the login screen or Settings to track your CBS-rostered players alongside Yahoo, ESPN, and Fantrax.
