Rickie Fowler held a three-way share of the lead following the completion of the rain-delayed second round at the OHL Classic at Mayakoba.
Fowler, who was one shot off the top of the leaderboard when play was suspended on Friday due to darkness following an earlier storm interruption, resumed on the 16th hole in Playa del Carmen and carded three consecutive pars.
The world number 10's four-under 67 leaves him 10-under overall, level with fellow Americans Patrick Rodgers and Patton Kizzire.
Seamus Power struggled badly on Friday and was four over par for the opening nine holes when conditions stopped play. He finished with a 73 to add to his opening 70 but it wasn't enough to escape the cut.
Kizzire, who held the first-round lead, was the only player to complete the 18 holes on Friday, while Rodgers, who produced four straight birdies on the front nine, managed a birdie and two pars from his three outstanding holes.
Play did not resume until 1pm local time on Saturday due to more bad weather.
Americans Brian Gay, Brandon Harkins and John Oda are all one shot off the pace in joint fourth, while Scotland's Russell Knox heads into the third round tied for 10th, four shots behind the leaders.
