The biggest recent swings in our MLB grades — who is climbing, who is sliding, and the deals where pay and value have drifted furthest apart.
A 162-game season is a slow reveal, and our MLB grades update right alongside it. Hot stretches, slumps, deadline trades, and new extensions all push the numbers — and this page tracks the biggest of those moves, up and down.
The Contract Value Index (CVI), our flagship contract-value grade, leads the board, since a single trade or contract can swing value the fastest. Performance movers follow, catching the production trends the stat line has begun to show.
It is a momentum board, not a ranking: which way a player is trending, not just where he stands.
Movers compare each player's two most recent grade snapshots over the last 30 days. We show how far the letter grade moved, never the underlying number. New deals and stat updates feed the next refresh.
Above-median MLB salaries carrying the weakest Contract Value Index (CVI) grades — the biggest gaps between what teams pay and what our grading says they are getting.

Every time our pipeline regrades a MLB player, it logs a snapshot. A mover is a player whose latest snapshot lands in a different letter tier than the one before it. We surface the largest tier swings — up and down — across the Contract Value Index and Performance grades. Grades shift as new games, contracts, and context arrive. Read the full methodology.
