You can figure out the payroll of a baseball team any way you want. There's the 40-man roster, the 25-man roster, you can add signing bonuses, other benefits, etc.
Here's how I'm doing it: The salaries for the 25-man roster plus any players on the disabled list. I also added in any bonus payments being paid this year. By that method, I have the Yankees with a payroll of $206,880,950 for this season.
It breaks down like this:
Alex Rodriguez: $33 million
CC Sabathia: $23 million
Mark Teixeira: $20.6 million
Derek Jeter: $20 million
A.J. Burnett: $16.5 million
Mariano Rivera: $15 million
Jorge Posada: 13.1 million
Johnny Damon: $13 million
Hideki Matsui: 13 million
Xavier Nady: $6.55 million
Robinson Cano: $6 million
Andy Pettitte: $5.5 million
Nick Swisher: $5.3 million
Chien-Ming Wang: $5 million
Damaso Marte: $3.75 million
Jose Molina; $2 million
Melky Cabrera: $1.4 million
Brian Bruney: $1.25 million
Cody Ransom: $455,100
Jose Veras: $432,975
Joba Chamberlain: $432,575
Edwar Ramirez: $422,500
Brett Gardner: $414,000
Phil Coke: $403,300
Jonathan Albaladejo: $403,075
Ramiro Pena: $400,000
You could add in the Major League contracts of Kei Igawa ($4 million), Andrew Brackman ($1.137,500) and Juan Miranda ($400,000). That would make it $212,418,450.
