Fourth seed Patty Schnyder was upset in the quarterfinals of the Proximus Diamond Games by unseeded Italian Karin Knapp who won 6-2 6-7 7-6.
The match was tight, and the 20-year-old Knapp almost spoiled the great opportunity to reach her first semifinal of the season as Schnyder’s experience started to dominate. Still, Knapp managed to defeat the favorite by gathering her power towards the end of the match. The Italian won the third set tiebreak 7-2.
The 13th-ranked Schnyder was playing an Antwerp quarterfinal for the fifth time, winning only one back in 2002.
World No.47 Knapp will next face either ninth seed Na Li of China or Sweden’s Sofia Arvidsson who advanced to the quarterfinals by upsetting second-seeded Anna Chakvetadze.
