The deal is believed to be a two year deal in the range of 12 million dollars.
DeRosa was coming off three strong seasons from 2006-2008 (one with Texas, two with Chicago). He hit a combined .291 with 44 home runs and a .368 OBP, before being traded to Cleveland around this time last year.
Looking back on it, the Cubs made a good move despite DeRosa's status with the team. On December 31st, 2008, the Cubs sent the fan-favorite DeRosa to Cleveland for pitchers Jeff Stevens, Chris Archer, and Jon Gaub. While the Cubs struggled to fill the hole at second in 2009, using at least five different second baseman throughout the year, they did make a solid move in landing two near-MLB ready pitchers in Stevens and Gaub, and an up-and-coming power arm in Archer.
He would primarily play third base, but be a reserve player at first, second, and the corner outfield spots.
