When Larisa Iordache was 14, the Romanian press dubbed her the “New Nadia,” in honor of Nadia Comaneci, the first female gymnast to score a perfect 10 at the Olympics. At 15, Iordache proved why she was worthy of the comparison: in her international debut this March, she placed third in the all-around at the American Cup and later helped Romania win a team gold at the Euro Championships in May. Iordache, now 16, lacks the consistency of some competitors, but her sensational tumbling — including a double twisting, double back on floor — and dynamic style will make her a viewer favorite in London.
