Kevin Youkilis to retire

BOSTON -- FormerBoston Red Soxinfielder Kevin Youkilis--"The Greek God of Walks" -- is walking away from the game, his agent said Thursday.

Youkilis played parts of nine seasons in Boston and was a part of World Series teams in 2004 and '07. He was traded to the Chicago White Sox in 2012 and then played an injury-shortened year with the New York Yankees before spending last season in Japan.

In his career, Youkilis had a .281 batting average with 150 homers and 618 RBIs. He also walked 539 times, a skill that earned him the nickname "Euclis, the Greek God of Walks" in the book "Moneyball."

Youkilis was a member of three all-star teams and received the 2008 Hank Aaron Award as the best hitter in the AL.
