The players were taken off the course mid-round after high winds at the iconic seaside course made the course virtually unplayable. Malnati was in pole position by two strokes at the time, sitting on 12 under with seven holes still to, play.
Fellow Americans Joseph Bramlett and Keith Mitchell were tied for second on ten under, with 36-hole leader Kurt Kitayama and Hank Lebioda a further shot behind.
The prevailing gusts were making it a lottery for the players. For example, Bramlett fired an 8-iron into the wind aiming for the 136-yard pin on the ninth and ended up short of the green. Then with the wind at his back on the 14th, Bramlett hit the same club over 210 yards up a hill and over the green.
"It's a guessing game," Bramlett told ESPN.
"We're just doing our best."
Mitchell had just toughed it out through the difficult ocean holes and emerged relatively unscathed when PGA TOUR vice-president of rules, Gary Young, ordered the horn blown, signaling the players off the windswept course.
"We knew going into today that those were going to be the tough holes," said Mitchell.
"That was going to be the hardest stretch potentially all week. If we could make it through that stretch in a relatively good score, I would be set up for the weekend."
Crowd favorite Jordan Speith was having a tough time of it, making the turn at three over for his round, putting him bang on the cut line.
Play is set to resume at 8am on Monday in order to complete the third round.
