Ymer M. vs Molleker R. prediction

This could be an interesting match between two really young players. Molleker is 170thon the ATP list and two years younger. He already has one title, on challenger in Heilbronn which is on clay. His score this year is 8-10, 5-2 on clay and his best reuslt is last week semifinal on challenger in Sophia Antipolis. He defeated here Robredo and Alcaraz, both in three sets. Ymer is 200th on the ATP list. His score this year is 13-5, 2-0 on clay, both matches here where he defeated Choinski and Brancaccio in two sets each. The only H2H match last year won Ymer, now I expect Molleker to win. Good luck
