Jhonny Peralta, who hit 24 homers last season and helped the Cleveland Indians contend in the AL, signed a contract extension that could keep the shortstop with the team through the 2011 season. The Indians said Friday the 23-year-old player signed a five-year contract through the 2010 season with a club option for the 2011 season. "Adding Jhonny Peralta to the current group of players already under contract solidifies a strong core of position players that will help to ensure a championship future," general manager Mark Shapiro said.
