Koepfer D. vs Mahut N. prediction

in second qual. round on us open koepfer will face with mahut. in previous round koepfer easy won against harrison in straight sets, and mahut was struggle with hard opponent cressy but he won at the end. in this match in my oppinion koepfer is better player, maybe his serve is not so good like mahut, but he move better on court,is better returnerand has better backhand. i think it will be enough to win
