David Goffin of Belgium won the last five games to complete a 6-3, 7-5 win over top-seeded Philipp Kohlschreiber in the second round of the Bet-at-Home Cup on Thursday.
The 78th-ranked Goffin held on to an early break to win the opening set and saved three set points for the German after dropping 5-2 down in the second. The match had been postponed Wednesday due to rain.
Goffin will play Paolo Lorenzi in the quarterfinals later Thursday. The Italian defeated last week's Gstaad champion Pablo Andujar of Spain 6-2, 6-0.
