While Zelenka's serve can be good, I would slightly disagree with
you, Jay Z, but not due to his speed and placement, but by the
fact that he overserves (and underserves) way too much. Sometimes,
2 or 3 times a performance, including singles underserves. Getting
the serve is play comes first...lol.
Though he's not playing to his caliber right now, I like Areitio's
serve. Doesn't get picked a lot, and he doesn't over or under
a lot, either, in doubles or singles.
Also, Urizar's serve at Orlando was terrific. He would loop it
up high, and slow, and get it deep and on the wall. Even if it
was picked, which was rare, he had time to get up in the court
if need be.
