Dustin Johnson, the world's No. 1 player, handled difficult conditions at TPC Boston for a 5-under 66 Friday and the lead of the PGA Tour's Dell Technologies Championship.
Johnson ended a five-month dry spell brought on by a bad back when he won the Northern Trust on Sunday.
Johnson played in the group featuring the top three in the FedEx Cup. PGA champion Justin Thomas made 16 pars in his round of 71. British Open champion Jordan Spieth, who lost to Johnson in a sudden-death playoff last week on Long Island, didn't make a birdie until his 13th hole and shot 72.
Masters champion Sergio Garcia opened with five birdies on the front nine and shot a 67, as did Jon Rahm.
Lewis takes lead, makes pledge
• Stacy Lewis shot an 8-under 64 for a share of the Cambia Portland (Ore.) Classic lead and said she'll give her winnings this week to flood relief efforts in the Houston area, where she grew up. Two-time defending champion Brooke Henderson (67) and first-round leader In Gee Chun (68) matched Lewis at 10-under 134.
• Kevin Sutherland shot an 8-under 62 to take one-stroke lead over Scott McCarron in the PGA Tour Champions' Shaw Charity Classic in Calgary, Alberta.
U.S. champ Gold seeks 'professional help'
U.S. figure skating star Gracie Gold is stepping away from the sport to seek professional help with the Olympics a little more than five months away.
The two-time national champion did not specify in a statement to U.S. Figure Skating what sort of help she needs.
"After recent struggles on and off the ice, I realize I need to seek some professional help and will be taking some time off," said Gold, 22.
McGregor-Mayweather numbers near record
Conor McGregor's improbable challenge of Floyd Mayweather Jr. was a hit at the box office, perhaps the biggest hit in history, with an estimated 50 million people watching in the United States alone.
Preliminary figures released by Showtime PPV showed sales of the fight tracking in the "mid to high" 4 million range, threatening the 4.6 million record set by Mayweather's 2015 fight with Manny Pacquiao. Estimating that 10 people watched each pay-per-view, Saturday's fight, won by Mayweather, was seen by 50 million, or nearly one in six Americans.
