Instead of beating up himself, the quick-tempered American roughed up defenseless Hamilton Golf and Country Club, shooting 8-under-par 62 on Thursday to take a one-shot lead.
“I get really mad generally,” Piercy said.
Greg Owen and William McGirt shot 63, and Robert Garrigus had 64.
Ernie Els, the British Open winner Sunday at Royal Lytham & St. Annes, opened with 72.
CHAMPIONS TOUR: In Turnberry, Scotland, Bernhard Langer shot 6-under-par 64 for a one-stroke lead in his bid to add a second Senior British Open championship to the title he won at Carnoustie two years ago.
“I was very pleased with the way I played,” Langer said. “Played smart. Hit some good drives, good iron shots and sank a few putts. Maybe left a couple of putts out there as well.”
Langer leads Mark McNulty, with Tom Lehman and Michael Allen among those at 66.
Tom Watson, bidding for his fourth British Senior title and his second at Turnberry, was among a group at 69. Greg Norman, Fred Couples and Mark Calcavecchia finished the day at 72.
LPGA/EUROPEAN LADIES TOUR: In Evian-Les-Bains, France, Stacy Lewis made seven consecutive birdies and tied the Evian Masters record with 9-under-par 63 in the opening round.
Her birdie flurry from holes 5-11, plus two more on 17 and 18, helped Lewis to a two-shot lead over Hee Young Park.
Lewis matched three-time champion Helen Alfredsson’s round of 63, set in 2008.
“I know I’ve made six (birdies) in a row before, but I don’t know if I’ve made seven … I almost made eight,” Lewis said.
It marked Lewis’ career-low round. Her previous low was 64, which she shot in the second and fourth rounds of the LPGA Classic in June.
EUROPEAN TOUR: In Atzenbrugg, Austria, Thorbjorn Olesen shot 4-under-par 68 to take a three-stroke lead over Thomas Levet after a shortened second day of the Austrian Open because of weather delays.
Olesen is at 12-under 132. Levet had 70 and was 135 overall.
Former Augusta State golfer Scott Jamieson completed both rounds, and is six shots off the lead after rounds of 71-67. Oliver Wilson opened with 68 and is 2-under through four holes of the second round.
Jamie Elson, another former Jaguar who opened with 79, is even through seven holes of the second round.
WEB.COM TOUR: In Columbus, Ohio, Trevor Murphy shot 8-under-par 63 to take the first-round lead in the weather-delayed Nationwide Children’s Hospital Invitational.
Of those that finished, Murphy leads James Sacheck by three shots.
Aiken native Matt Hendrix is 2-under after eight holes and Augusta’s Scott Parel is 1-under after 13.
