METZ, France (AP) American Sam Querrey lost to Frenchman Gilles Simon 6-4, 7-6 (1) Friday in the quarterfinals of the Moselle Open.
Simon took control of the tiebreaker by hitting a forehand passer down the line to open up a 3-1 lead.
He then forced an error at the net from Querrey, who swiped his racket in frustration after losing the next point. Simon hit a crisp forehand winner that set up five match points and he converted the first when Querrey's shot sank into the net.
Simon, who did not face a single break point, will play Nicolas Mahut. He beat Germany's Benjamin Becker 6-2, 6-4.
