LAKE BUENA VISTA, Fla. — A baseball source confirmed that the Red Sox and newly acquired first baseman Adrian Gonzalez have agreed to the framework of an extension that will pay the slugger roughly $22 million a year for seven years. The extension, which will likely wait be announced after the start of the season both so the Sox can ensure that Gonzalez’ right shoulder is healthy and so that they can diminish their luxury tax hit, would run from 2012-2018. Gonzalez will play this season for $6.2 million, the option year on a four-year contract he signed with the Padres for the 2007-10 seasons.

Ken Rosenthal of FoxSports.com was the first to report the seven-year, $154 million framework, which would ultimately result in Gonzalez being paid just over $160 million over eight years in Boston.
