StarterWatch
A fantasy-baseball sidekick that alerts you the moment a starting pitcher does something your lineup can't ignore — perfect games, no-hitters, early pullings, pitch-count spikes.
Fantasy baseball managers in head-to-head or category leagues who can't watch every game
- Push alerts for in-game milestones (perfect through 5, 10+ strikeouts, pulled before 80 pitches) with context on why it matters
- Matchup grade before each start based on recent velocity, swing-and-miss rate and opposing lineup handedness
- Lineup-lock reminders tied to probable starters so you never bench a hot arm on accident
- Weekly recap digest explaining what your roster missed and who to pick up on waivers
