Grady Sizemore signed a Major League contract worth $750,000 with the Boston Red Sox, but he has the ability to make as much as $6 million.

Sizemore will make $250,000 if he makes the Opening Day roster, and then $250,000 each time he reaches 60, 90, 120 and 150 days in Major Leagues.

The former Cleveland Indians outfielder will also make $250,000 for increments of 25 plate appearances, starting at 225 and stretching to 500.

The remainder of the potential $6 million can be earned through individual award incentives.
