Career Highlights: Zelenka and teammate Sara Hendershot will each make their Summer Games debut in London after winning June's Olympic trials. Zelenka, a native of Itasca, Ill., had thoughts of competing in basketball in college, but her attention turned to rowing when she arrived at Grand Valley State. She was named team MVP as a junior and senior. Zelenka finished first in the fours at the 2011 world championships - two years after taking sixth in that event at the U-23 championships.
