METZ, France (AP) Eighth-seeded David Goffin of Belgium rallied to beat top-seeded Jo-Wilfried Tsonga 1-6, 7-6 (5), 7-5 Friday to reach the Moselle Open semifinals.
Goffin next plays Germany's Jan-Lennard Struff, who advanced after third-seeded Philipp Kohlschreiber retired when trailing 5-0 after just 20 minutes.
Looking to win the Moselle title for the third time, Tsonga dominated the first set, hitting five aces and converting both of his break points.
The players traded breaks in the third set before Tsonga saved two break points at 15-40 down in the 11th game. But he missed a chance to win it and Goffin seized his next opportunity before serving out victory on his second match point.
Goffin's only career title was on outdoor clay in Kitzbuehel, Austria in August.
