Youkilis signs four-year deal worth over $40 million

Peter Gammons is reporting that Sox first-baseman Kevin Youkilis has signed a four-year pact worth over $40 million, or over $10 million per year. The deal includes an option for a fifth year.

Youk was slated to be a free agent after 2010. This keeps him in Sox red (presumably) until at least 2012.

It’s quite a deal considering Youkilis has outproduced Mark Teixeira (yes, it’s true, according to an GM and some metrics) the last two years.
