Playing devil's advocate for the original poster, the Garza offer could have been followed by a trade of Correia, Burton, Willingham, etc., which would have mostly neutral payroll implications. We really don't know much about its context.
I am encouraged by the Garza offer, but it's a pretty small data point so far for the trend we all want to see -- more investment in the big-league roster.
Which is fine to want to see more spending... But the Twins payroll isn't necessarily at $80m because the Pohlads have demanded that to be the case.
The Twins couldn't make up Garza's salary through trades. Correia could be traded, sure. Burton, probably, but he's not making much. But nobody is taking Willingham at this point, not for $7m.
