We think the match John Isner against Horacio Zeballos shouldn't bring a Big Man any troubles and will allow him to warm up and feel the court at the beginning of the US Men's Clay Court Championship in Houston.
Argentinian's current ATP rankings is #117 and he is definitely a clay court specialist. He has met with Isner two times, they played on clay in both matches and both times Zeballos was beaten. It is worth noticing that Horacio was in a better form than he is now, while John had a very little experience on clay those days, and still he managed to win. This season Isner has already won against several strong rivals on clay, including Federer, and proved that his serve, movement over the court can be as strong and confident as on hard surface. He also showed a smart game with a wide scope of skillful combinations. That's why we came to conclusion it's unlikely that John would give even one set.
Pick: John Isner 2-0
