The clutchiness numbers
have finally been updated, and are now current through July 29th.
A note on traded players: all the numbers you see for a player are his stats with that team. When a player amasses ten at-bats with a new team, his numbers will appear on that team's page, and will be taken off his old team's page. So for all the most recent trades (Carlos Lee, Bobby Abreu, etc.), as of this update, they're all on their old clubs.
