That might not be low enough.
Langer shot 6-under-par 64 on Saturday to move to 10-under for the tournament, putting him ahead of a big-name field by four strokes.
“That’s not a huge lead,” Langer insisted. “That can disappear in no time. I’m going to have to get out there and shoot under par. That’s my goal.
“If I go 2-under or 3-under, it will be very difficult for anyone to catch me. And if they do, they deserve to win.”
The two-time Masters Tournament champion opened with three consecutive birdies and eight in 12 holes at Indianwood.
“He didn’t win two Masters by luck,” said Corey Pavin, who is in a five-way tie for second place. “He’s an exceptionally good player, very methodical.”
Pavin, Tom Lehman, Roger Chapman, John Huston and Tom Pernice Jr. are at 6-under 204.
Couples had 65 and is in a group five shots back.
Second-round leader Lance Ten Broeck, a full-time caddie for Tim Herron on the PGA Tour, shot 72 and is alone in 11th place, six shots back.
U.S. AMATEUR PUBLIC LINKS: In Midway, Utah, T.J. Vogel took things down to the wire in match play three times this week to advance to the next stage at the U.S. Amateur Public Links Championship.
If his play in the final Saturday is any indication, the University of Florida senior must have grown tired of seeing victories hinge on the final hole.
Vogel made six birdies over a seven-hole stretch and coasted to a 12-and-10 win over Kevin Aylwin, earning a spot in the 2013 Masters field.

Soren Kjeldsen and Marc Warren, who holed an 80-foot putt for eagle on No. 16, are two strokes behind Molinari after 64s – the lowest rounds of the day along with Martin Laird.
Hansen upstaged his top-ranked playing partner Luke Donald (68), while Phil Mickelson also had a 65 to join three others trailing the leader by three shots.
WEB.COM TOUR: In Sandy, Utah, Michael Putnam reeled off five birdies in a row on the back nine and shot 8-under-par 63 to take a four-shot lead in the Utah Championship.
