End of career (2008–2009) On May 28, 2008, Sosa announced that he instructed his agent not to offer his services to any MLB team for the 2008 season, and planned on filing for retirement, but never did. On December 25, 2008, Sosa announced he intended to unretire and play in the World Baseball Classic and once again test the free agent market in hopes of signing with a Major League ballclub in 2009. Sosa said that he had been keeping in shape at his home, and was hoping that after a strong World Baseball Classic he would prove to major-league teams that he was still capable of playing in MLB. However, he was not selected as part of the Dominican Republic's roster. He remained a free agent and did not actively look for a team.
