Sammy Sosa is seriously considering retiring from baseball instead of accepting an offer from the Washington Nationals, a source close to the player told ESPNdeportes.com. Sosa has not made a decision regarding the contract offer from Washington, which is a non-guaranteed, one-year pact for $500,000. "Sammy doesn't think of himself as someone who has to beg for a spot on a big league roster," said the source. Washington's offer is the only one the Dominican slugger and potential Hall of Famer has received this winter. With 588 career home runs, Sosa is the all-time leader among Latin American players. He had three years of 60 or more home runs between 1998 and 2001 as a Cub, becoming enormously popular in Chicago and throughout baseball. However, injuries and some bad publicity, including the discovery of a corked bat in 2003, have affected his legacy and market value. "Sammy wants to get to 600 home runs, but he's not willing to humiliate himself to keep playing. He feels that the lack of interest in his services this winter constitutes a humiliation," added the source.
