Marchenko I. vs Ebden M. prediction

1st round at the atp Busan challenger will offer a duel between Marchenko and Ebden.I belive Marchenko has a lot more chances to win in this match. Marchenko is currently on the 122. place at the ATP rankings.His has very good serve that is his biggest weapon.He has poor results this year as he has 4/10 record.He played last week in Seul where he lost to Fabbiano in straight sets.He had some good wins this season against Gabashvili,Rublev and Halys. Ebden is currently on the 302.place at the ATP rankings.He has 14/9 record this year,and 5/5 on hard surface.He easily lost to Nguyen last week in qualification for challenger in Seul.I don`t know what happened but that loss was amazing. I belive Marchenko can win in this match,because Ebden is playing in bad form,and I rate Marchenko as a better player.
