D. Thiem - S. Johnson Tennis prediction

In second round of USO  we have a match between D. Thiem (ATP #9) and S.Johnson (ATP #31). S.Johnson played a good tennis in Winston-Salem . Finished as runner-up , lost just to russian D. Medvedev. What i notice in match  that Steve has a very weak backhand, he never attacks with backhand  just defending all the time, and that didnt worked out in final of Winston-Salem. D. Thiem is better overall player, he must be more hungry than American guy. Johnson grabbed his points  in previous tournament  and i think here in USO  D. THIEM  will go to another round  because of his good serve  and he is just 24   and is #9 in world  he need to win to stay at top 10.
