Scotti Chefler is one on the first road on the right track for his first victory this year, as he extended his progress to six shots in the second round affected by the storm of CJ CUP Byron Nelson.
A play was placed on Friday in Texas for more than six hours, and many players did not complete the second round, as 18 players were not performed.
American Scheffler got eight years 63 in TPC Craig Ranch to move to 18 under the lowest total 36 hole in his career in the PGA tour.
Its common result, which reached 124 after 61 on Thursday, is the second happiest 36 hole in the history of the round after Justin Thomas 123 in the Sony Open 2017 championship.
America, Sam Stevens is second in 12 below, with the resumption of the second round on Saturday, followed by the third round.
