Pedro Martinez said some of his Phillies teammates were suffering from swine flu during Philadelphia's 2009 World Series, reports the Philadelphia Inquirer.
Martinez threw a ceremonial first pitch Sunday as he celebrated the 10th anniversary of their National League championship with his former teammates.
"It wasn’t told, but most of us were sick," Martinez said. "Some of the guys had swine flu and had to be kept away. I caught some of the virus. We would just never say it. When I got home, I realized that I was really sick."
Martinez started two of the six games against the Yankees.
