Boston, MA (SportsNetwork.com) - The Boston Red Sox signed three-time All-Star outfielder Grady Sizemore to a one-year contract on Wednesday.

The deal is reportedly worth $750,000 and can be worth up to $6 million with incentives factored in, according to CBSSports.com.

Sizemore hasn't played in the majors since 2011 due to multiple injuries and surgeries. He has undergone seven surgeries since the '09 season.

Before the injuries, Sizemore was one of baseball's premier outfielders during his time with the Cleveland Indians. He hit .290 while leading the majors in runs (134), doubles (53) and extra-base hits (92) in 2006. With 11 triples and 28 home runs that year, Sizemore became just the fourth player with a 50- double, 10-triple, 25-homer season.

The 31-year-old followed that with a pair of Gold Glove campaigns. From 2006-09, he ranked second in the American League with 426 runs scored and 276 extra-base hits.

Sizemore is a lifetime .269 hitter with 216 doubles, 43 triples, 139 homers, 458 RBI, 134 stolen bases and 601 runs scored in 892 games -- all with Cleveland -- from 2004-11. He was named an American League All-Star in each of his last three full seasons from 2006-08.

To make room on the 40-man roster, Boston designated pitcher Brayan Villarreal for assignment.
