Siemerink, Rosset Reach Semis




ST. PETERSBURG -- Top-seeded Jan Siemerink of the Netherlands advanced to the quarterfinals of the St. Petersburg Open, defeating Fredrik Jonsson of Sweden 7-6 (7-2) 6-2 on Thursday.


Siemerink, who lost in the first round at the Qatar Open and Australian Open, won 88 percent of his first service points and never faced a break point. He goes on to face Igor Korniyenko of Russia.


Last year's runner-up Marc Rosset of Switzerland, seeded second, also reached the final eight, eliminating Sebastien Grosjean of France 6-2, 7-6 (7-2) Thursday.


Germany's David Prinosil upset fourth-seeded Magnus Gustafsson 4-6, 6-3, 6-4 and Russian Marat Safin, seeded fourth, advanced too by beating Mikael Tillstrom, Sweden, 6-3, 6-4, earning a roaring ovation from the Russian audience.


Peterburgsky Stadium officials were scrambling to keep the building heated as temperatures outside dipped to minus 28 degrees Celsius on Thursday.


The stadium became another casualty of Russia's financial troubles when the local electricity provider cut off power right before the tournament because of unpaid energy bills, causing heating pipes to burst.
