Davis was again around in 68 on day two to be at 6 under but such is the quality of the scoring on the Greg Norman designed layout that he is in a share of 44th place.
Jones began the event with a round of 65 but it was a very much different story today as he struggled to a round of 73 to fall from a share of 4th to 62nd and just inside the cutline.
Kuchar has not won a PGA Tour title in more than four years but today he produced five birdies in his first six holes to set up a round of 64 to follow the one he produced on Thursday.
As good as his effort was there were moments where he found trouble but in the one moment that might have brought his round undone he found a way to save bogey (see video below).
If Kuchar was able to go on and win it would be a great boost for next week's Australian Open where is is an invitee in a field weakened by the absence of several of Australia's leading players. He will also represent the USA at the World Cup in Melbourne the following week.
Rookie sensation Champ has again highlighted his significant potential with a round of 62 to move into outright second position while the improving New Zealander Danny Lee is in a large group in a share of 3rd place.
Lee recently celebrated the arrival of his first child, Roi Theodore, and fatherhood appears to be agreeing with him with a series of solid finishes in recent weeks.
Champ won the Sanderson Farms Championship two weeks ago and his rapidly building fan base as a result of his exceptional length from the tee will build further this week.
Curtis Luck was the other Australian in the field but the PGA Tour rookie has missed the cut by several shots.
