England's Ashley Chesters remained the man to catch in the Andalucia Masters, despite not hitting a single shot on a second weather-affected day at Valderrama.
After four hours were lost to stormy conditions on Thursday, two further delays on Friday meant half the field, including Chesters, defending champion Sergio Garcia and Ireland's Shane Lowry, had yet to begin their second rounds.
Play was due to resume at 9.10am local time on Saturday but with more bad weather forecast, the tournament could be extended until Monday or reduced to 54 holes.
The European Tour will be keen to complete as many rounds as possible as the €2 million event is the last chance for players to reach the top 116 on the Race to Dubai and secure full playing privileges for next season.
Scotland's Marc Warren, who began the week 144th on the money list, is a shot off the lead after playing the first nine holes of his second round in two under par, with France's Gregory Bourdy alongside Warren on four under after an opening 67.
Home favourite Gonzalo Fernandez-Castano is part of a five-strong group on three under after seven holes of his second round, but the 38-year-old will return to an eagle putt on the par-five 17th when play resumes.
Fellow Spaniard Alvaro Quiros and Welshman Oliver Farr were also on three under in the early stages of their second rounds, alongside Garcia and Australian Jason Scrivener, who were due to start their second rounds on Saturday.
Warren, whose sole top-10 of the season came in the Spanish Open in April, said: “I’m hitting the ball as well as I have in a long time. I gave myself a lot of chances and I’m doing what you’ve got to do around here, which is hitting fairways and greens.
“I managed to stay patient and got the rewards with being two under for the round this afternoon. Hopefully I wake up tomorrow with the same swing and swing thoughts as I had today.”
Pádraig Harrington got through 19 holes on Friday, completing his first round in one-over 72. He remained on the same mark through nine holes of his second round after a birdie on the 10th and a bogey on the 14th.
Gavin Moynihan finished his day with back-to-back birdies to move back to level par for the tournament after five holes of his second round. He had earlier carded a two-over 73 in his first round.
Lowry, who completed a two-under 69 on Thursday, will start his second round at 11.20am local time on Saturday.
