On July 31, 2009, Rolen was traded to the Cincinnati Reds along with cash considerations for Edwin Encarnación, Josh Roenicke and Zach Stewart. During the 2010 season, Rolen regularly started at third. He hit his 300th career home run on June 28, 2010 off Kyle Kendrick of the Philadelphia Phillies. His performance helped the Reds win the Central Division that year, their first division championship in 15 seasons. Rolen also won his eighth Gold Glove as a member of the Reds, the third team with which he received the award.
