Karlsson and Stadler lead in Mexico

Robert Karlsson and Kevin Stadler shared the lead when play was suspended for the day during the second round of the OHL Classic at Maykoba.

Stadler shot an eight-under-par 63 in Friday's second round, while Karlsson carded a 67 as both players lay on 12 under.

Rory Sabbatini and Chris Stroud both lay three shots back but had not completed their round when play was halted due to the dark. Sabbatini had played 17 holes and Stroud 15.

Ryan Moore, Jhonattan Vegas, Pat Perez and Jay McLuen were a shot further back on eight under.

Only 26 players had completed the second round following two weather delays on Thursday and one more on Friday.
