Source: Myers deal with Astros will be two-yr extension through 2012 with club option for '13. Option also will have vesting element.
— Ken Rosenthal via Twitter - take this with a grain of salt, but it is the first actual bit of news we've gotten on the extension. McTaggart just tweeted that Myers is looking for a third year as a guarantee. I think these two reports explain why there has been no news, officially, on the deal since 2:30 PM.
