I've compiled 2010 starting rotation spending by team; details can be found in this spreadsheet. Buyouts (for example, the $2.5MM the Dodgers owe to Jason Schmidt) and players not in 2010 rotations (Kei Igawa) are not included in the figures below. If a team is paying part of the salary of another club's starter, like in the case of Roy Halladay, that payment is accounted for only on the receiving team. If you find any errors, please contact us.
