Nadal Rafael - Del Potro Juan-Martin

Wimbledon qualification begins and here I take Harris 2:0.
Harris's playing style:
He heavily relies on his first serve, short points, often comes to the net after a good serve, aggressively hits from the forehand side and, as he himself has mentioned, his favorite surface is grass, where he feels better.
His pros here: being a host player, he has a lot of experience on British grass, a powerful serve, plays well at the net, and has good first 2-3 shots after the serve.
His con is that if his first serve percentage drops significantly, he is not as strong in longer baseline rallies. But after all, this is grass, so he should maintain a decent percentage. His form is not bad, he looked decent last week at Nottingham.
Napolitano's style:
His height of 1.96 also gives him a decent serve, but not as good as Harris's.
He is more of a baseline player, enjoys the rhythm from the back of the court, feels better on slower surfaces rather than on very fast grass. He has also spent a large part of his career playing challenger tournaments on clay and hard courts.
His cons are that he is not strong at the net, and overall, his movement on grass is not his strong suit. On grass, he often struggles to take the initiative against strong servers like Harris. So, I would say he is not a favorable opponent for Harris. As he showed playing on hard courts, defeating him 7:5 6:3. On grass, Harris is even more of a favorite.
