Part of a strong Russian contingent competing at the world junior championships, Openysheva may stand at a petite 1.61m, but her explosiveness in the pool cannot be underestimated. The sprint specialist won seven golds at the inaugural European Games in June, and is the top seed in the 100m and 200m freestyle.
