N. Kyrgios vs R.Nadal prediction

Kyrgios is obvious in a great shape. He has beaten Wawrinka, Cuevas and Raonic in last 10 days. He has big serve and likes big matches. He is ranking 20th place and this is the highest ranking for him. However, Krygios has 10-14 record against Top-10 players and his last 4 matches ended up more than 21 games. There have been 5 tie breaks that he played in last 7 sets. It shows that how hard to break his serve with his recent form. On the other hand, Nadal has dramatically lost semi final game in home country against Murray and is looking for great pace before Roland Garros in Paris. I do expect a tie break in first set and we will watch more than 21 games in a match.
