The first match for John Isner in the quarterfinal of Davis Cup will be against Gilles Simon (ATP ranking #13), with whom he already played this season. Simon has a wide experience on various surfaces including clay, so this time a court as well as home advantage belongs to him.
The head-to-head stats is 2-0 for Isner, he defeated Simon in 2011 at the US Open and in Indian Wells this year, both times on hard court. Despite this match is held on clay, which is Simon's favorite, we think John Isner has a great chance of winning. He already beat Federer on the same surface earlier in Switzerland in the first round of Davis Cup 2012 and showed a good performance in general.
Pick: John Isner to win
