Aaron Gleeman notes the Twins made little progress in signing Justin Morneau to a long term deal. I agree with this:

At one point last season Morneau said that he'd be willing to sign a five- or six-year extension to remain in Minnesota, but reportedly turned down an offer from the Twins that was similar to the four-year, $33 million extension that Joe Mauer agreed to last winter. As good as Morneau has been and can be, his .276/.340/.498 career hitting line is just slightly above average for an MLB first baseman and paying that type of player something like $12 million per season would be risky for a team like the Twins.

It's equally risky for Morneau. If his seven great months of hitting prove to be the height of his career, he'll have wished he took that four year extension.
