Field notes
No Curveball groups live game context with longer-term player behavior rather than presenting isolated box-score stats. Its change feed surfaces dated shifts such as exit-velocity movement, while the leaderboard views expose qualified CSW% and xwOBA figures with pitch counts. The homepage also distinguishes current starter readings from season baselines for velocity, induced vertical break, and pitch usage, giving readers a compact way to inspect what is changing.
