(Reuters) - A pair of Major League Baseball games scheduled to be played in Puerto Rico later this month could be relocated due to growing concerns over the Zika virus in the area, the MLB Players Association said on Tuesday. The Miami Marlins and Pittsburgh Pirates are scheduled to play two games in San Juan on May 30-31 but the series is in doubt with nearly 700 confirmed cases of Zika in Puerto Rico. Zika, a virus known to cause the birth defect microcephaly, first began spreading in Puerto Rico in December.
