Brandt Snedeker, now in 11th place in the standings, lost precious points when he bogeyed the last hole and fell into a tie for third with Tiger Woods at the British Open.
The top eight going into the Canadian Open are Woods, Masters Tournament champion Bubba Watson, Jason Dufner, U.S. Open champion Webb Simpson, Zach Johnson, Matt Kuchar, Phil Mickelson and Hunter Mahan.
PGA champion Keegan Bradley is at No. 9, though he is the equivalent of $640,000 behind Mahan.
Each $1,000 in PGA Tour earnings is worth one point, and it’s worth double that in the majors.
The qualifying ends with the PGA Championship on Aug. 12, and captain Davis Love III would have three more weeks before making his four wild-card selections.
Among those outside the top eight are Steve Stricker, who has played on the past two teams, and Jim Furyk, who has played on every team since 1997.
Both of them would have to win either the Canadian Open or Bridgestone Invitational, or come in third at the PGA Championship.
Rickie Fowler is at No. 10, Dustin Johnson is at No. 12 and Bo Van Pelt is at No. 14.
Former Clemson star Kyle Stanley has an outside shot at 18th place.
Augusta native Charles Howell is 40th.
