Kitzbuhel, Austria (SportsNetwork.com) - Top seed Philipp Kohlschreiber and third-seeded Lukas Rosol were among the losers Thursday at the Kitzbuhel Cup.
Belgian wild card David Goffin upset the German 2012 runner-up Kohlschreiber 6-3, 7-5 to reach the quarterfinals on the red clay at Kitzbuhel Tennis Stadium.
Goffin then beat Italian Paolo Lorenzi 6-2, 6-1 to reach his first-ever ATP semifinal, as several players were forced into double duty on Thursday after rain wreaked havoc here on Wednesday.
Rosol gave way to Argentine qualifier Maximo Gonzalez 6-3, 4-6, 6-4 in a quarterfinal affair, as Gonzalez will face Goffin in Friday's semis.
In other second-round action involving seeds, No. 2 Spaniard Marcel Granollers mauled Argentine Diego Sebastian Schwartzman 6-3, 6-4; No. 4 Italian and 2010 champion Andreas Seppi advanced via walkover when Spaniard Pere Riba pulled out of the draw; No. 5 Austrian favorite Dominic Thiem dismissed Czech Jiri Vesely 6-3, 7-6 (7-3); and Argentine Juan Monaco tackled No. 7 Finn Jarkko Nieminen 6-3, 6-4.
One other second-rounder saw Lorenzi douse Spaniard Pablo Andujar, last week's Gstaad champion, 6-2, 6-0.
Two more quarterfinals on Friday will pit the reigning Kitzbuhel champ Granollers against Thiem and Seppi versus last week's Gstaad runner-up Monaco. The winners will meet in the other semifinal. Monaco was the Kitzbuhel titlist back in 2007.
This week's winner will claim $104,000.
