Pablo Larrazabal overcame a lengthy rain delay to shoot an 8-under 64 to take the clubhouse lead on Wednesday before the opening round of the Austrian Open was suspended because of darkness.
The Spaniard hit four birdies and an eagle to sit at 6 under after 12 holes when play was suspended for 3 hours, 40 minutes. He then added two more birdies to equal the course record set by Jose Manuel Lara of Spain when he won the 2010 tournament.
Play was later suspended for the day, with Thorbjorn Olesen of Denmark closing in on Larrazabal at 7 under after 14 holes. Thomas Levet of France and Wil Besseling of the Netherlands were at 6 under.
Scotland's Alistair Forsyth and England's Oliver Wilson hit 68s, while defending champion Kenneth Ferrie of England was par after 14 holes.
Former top-ranked tennis player Yevgeny Kafelnikov, appearing in his second European Tour event after the 2008 Russian Open, shot a 75 to outscore two former champions. Lara shot a 78 and 2006 winner Markus Brier of Austria hit a 76.
