Elias Ymer is great talent. He started to made impression from 2013 when won a set on ATP Bastad against G.Dimitrov. He has good first serve and powerful forehand but has to work a lot on his footwork on hard courts. Santillan is hard court specialist and his game suits the surfaces most. He is playing mostly on Futures level but very successfully. Last year managed to win a set against R.Stepanek in the qualifications of ATP Tokyo. He has excellent footwork for the hard courts and he is very solid from the base line. The Japanese likes to counter by using the paste of his opponent’s shots. I see Ymer to hit two three powerful shots and if he managed to win the point ok, but in the most rallies the better consistence of Santillan will help him to win the point and eventually the whole match.
