By shooting 3 over in the last 12 holes, List carded a 73 and was tied for fifth at 8 under.
What the travails say is that just about anything can happen on the finishing stretch at Torrey Pines, and it could get more interesting with Santa Ana winds on Sunday that are forecasted to blow up to 20 mph as the temperature rises to an unseasonably toasty 82 degrees.
"Sundays at Torrey Pines, U.S. Open golf course, anything can happen, so I'm glad I shot under par" said Jason Day, the 2015 Farmers Open champ who scored 71 and is in the hunt at 8 under.
Last year, 20 players had a chance to win the tournament halfway through the final round. This year, there are 16 golfers four shots or closer to the lead to begin Sunday.
J.B. Holmes, who started on the 10th hole Saturday, shot a stunning 29 on his second nine of the South and finished with a 7-under 65 to be tied for third place with Michael Kim (70), a 24-year-old San Diegan who played high school golf matches at Torrey Pines.
Among those in a seven-way tie for fifth are two former Junior World winners at Torrey Pines -- Day and Beau Hossler, who shot 69 and hasn't made a bogey over his last 45 holes.
The leader, Noren, is a 35-year-old Swede who is virtually unknown to anybody who doesn't follow the European Tour. But he's had plenty of success there, with nine wins, including six since 2015.
He hadn't played Torrey Pines until this week.
"I've dreamt of winning of the U.S. Tour," said Noren, who competed in college at Oklahoma State.
He said he doesn't mind being the player fans don't recognize.
