Cutting things close is very different than not having (your original declaration) the revenue streams.http://www.forbes.com/lists/2009/33/baseball-values-09_Philadelphia-Phillies_335119.html
According to the stats from 09 they are cutting things pretty close are they not?
I'd call it spending money, to make money. Building a successful franchise on the field leads to even more revenue via being able to charge more for tickets (superior product and increased demand), more post season revenue, increases in merchandising and local broadcast revenues and all of those go towards increasing the value of the franchise if and when the owner decides to sell.
Sounds to me like they know exactly what they are doing.
