The following table shows what our payroll situation would be if we built a team from what we already have in-house. Some figures are exact, and others, such as those of the arbitration-eligibles, are approximations.
(Don't worry about things like, say, Jason Vargas showing up instead of Garret Olson. It doesn't matter.)
Right now we're looking at salary commitments totaling $65-70m. The 2009 Mariners cost about $99m, so assuming a fairly similar but slightly reduced budget going forward, that leaves us with $25-30m of room to play with, with a number of spots at which we could stand to improve.
Damn you, Carlos Silva.
