It will be a wet final round for Listowel's Corey Conners and company at The Northern Trust in Jersey City, New Jersey.
Conners matched a career low on Saturday with 9-under-62.
Sunday's action was washed out by rain from Tropical Storm Henri.
According to a release from the PGA, the course received over 152 mm of rain overnight Saturday into Sunday. And more rain was expected into Monday.
The final round was originally scheduled to tee off at 7:30 a.m. Monday. But more rain pushed that start time back further to 10:30 a.m.
Conners is tied for 9th at 12-under, four shots back of the leaders, Australian Cameron Smith and Spain's Jon Rahm.
