i think Nadia. They are both in th etop to for ETA U14. They have just started playing U18's this year, Nadiya has 1 Tournament win and a couple runner-ups, while Lyudmyla has a Runner-Up and a couple Semis. They play mostly Grade 3 and 4 tournaments.
Nadiya and Lyudmyla both participated in the European Summer Cup for Ukraine. They both played singles and doubles. Ukraine won the Zone D which included Russia. But Came in 3rd place in the Final Rounds after losing to France in the Semi's! Lyudmyla lost only 1 singles match in 6 rounds and Nadiya only lost two. Nadiya played more doubles with the third player on the Ukraine team which made her more tired than Lyudmyla.
