Robert Karlsson remained on track to complete his leg of a Swedish double this weekend by retaining a share of the lead after the third day of the OHL Classic at Mayakoba.
The 44-year-old, who won the European Order of Merit back in 2008, was on 15 under after seven holes of his third round when darkness halted play in Mexico.
He will return to the El Camaleon course on Sunday as his compatriot Henrik Stenson looks to wrap up victory in the DP World Tour Championship and secure the Race to Dubai.
Karlsson is three under for his round so far after three successive birdies from the third which put him alongside American Harris English who has also birdied three of his seven holes so far.
English, who won the St Jude Classic in June for his first PGA Tour title, had earlier posted a superb nine-under 62 when completing his second round, equalling the lowest round of his career.
The pair are three shots clear of South African Rory Sabbatini who is on 12 under after eight holes, the same score as American Kevin Stadler who had shared the overnight lead with Karlsson.
Spain's Alvaro Quiros is making a third-round charge after six birdies in a flawless 14 holes took him to 11 under and joint-fifth place with American duo Jason Bohn and Chris Stroud.
Northern Ireland's Darren Clarke is in a tie for 44th place on four under and is one under after 13 holes of his third round.
