Home-run king and Most Valuable Player (MVP) Sammy Sosa told Hoy newspaper last night that, as much as he would like to do it, prior commitments in Puerto Rico and the U.S. preclude his participation in the Dominican delegation to lobby for Santo Domingo to host the 2003 Pan American Games. It was announced yesterday that Sosa had been invited to accompany the delegation, and the news sparked considerable excitement in Panama City, where the Pan American Sports Organization (ODEPA) is due this weekend to decide on the site for the 2003 PanAm Games. Sosa told Hoy that he wants to help his country in every way possible, but he cannot back out of the commitments he made weeks ago.
