From a March 2005 article by Jeff Passan in the Kansas City Star:
“He was born with them,” said Jan Scherzer, Max’s mother. “Then he was 4 months old. I looked down at my baby, and he had a blue and green eye. Very clearly. I have pictures and everything. I took him to the pediatrician shortly after that, and he said, ‘They may go back and forth. They may change again this year.’ As the year went on, the blue eye got bluer, and the green eye changed to brown.“And it was amazing. That night, on Johnny Carson, the actress Jane Seymour was on. She had different-colored eyes. It was just such a coincidence. She was talking about all the flak she’d taken growing up. She’s a beautiful woman. She did OK. We always made a big deal to Max that he was special, that it wasn’t something wrong.”In grade school, when Max drew a cat or dog or giraffe, he always chose dissimilar colors for their eyes. On parent-teacher night, Brad and Jan could immediately tell which drawing hanging on the wall was their son’s.Teasing in middle school gave way once Scherzer’s reputation as a top athlete grew in high school. As a freshman, he started at quarterback for Parkway Central High near St. Louis. He played varsity basketball, too, but baseball occupied most of his time.
Scherzer’s heterochromia has been reflected in several anatomically correct bobbleheads, including a large figure outside of Detroit’s Comerica Park.
Scherzer has also sported heterochromatic goggles in the clubhouse after big wins for the past three years.
