About RosterRadar

Stop watching the wrong baseball game. RosterRadar is RedZone-style MLB coverage built around your fantasy roster, player props, and the players you care about most. It scans the live slate, finds the at-bats that can change your matchup or your night, and can drive MLB.TV straight to the action before you miss it. Connect ESPN, Yahoo, or Fantrax. Add players manually. Flip on Auto Tune. Then let RosterRadar chase the moments worth yelling at your screen for. Built for serious fantasy baseball managers, RosterRadar turns Chrome into a live command center for the MLB slate. Every active game is ranked by fantasy impact, so you can see where your starters, your opponent's players, your picks, and your must-watch moments are happening right now.

RosterRadar tells you which one matters right now. Instead of bouncing between tabs, checking box scores, and guessing where the next big plate appearance is, RosterRadar builds a live leaderboard around the players that matter to you.

Turn on Auto Tune and RosterRadar can switch your feed automatically. It is like having a producer for your fantasy baseball night, except the producer only cares about your roster.
