Dustin Pedroia and the Red Sox have agreed in principle to an extension that would keep the star second baseman in Boston until his mid-30s.

WEII.com's Rob Bradford reports the deal is worth $100 million — the most ever for a second baseman — and will stretch until 2021, with Pedroia owning a full no-trade clause.

Pedroia has been a franchise cornerstone in Boston since his rookie year in 2007, when the Red Sox won the World Series and he won American League Rookie of the year after hitting .317. The next season, Pedroia hit a career-high .326 with 54 doubles and scored 118 runs to win Most Valuable Player.

The 29-year-old Pedroia currently leads all AL second basemen in hits (121), doubles (25) and walks (51) and is third in RBI (57).
