Canadian teenager Brooke Henderson leads LPGA event in Portland

Canadian teenager Brooke Henderson birdied three of her last four holes for a five-under-par 67 and the second-round lead in the LPGA Tour’s Cambia Portland Classic in Oregon.

The 17-year-old Henderson had an 11-under 133 total at Columbia Edgewater for a one-shot lead over Caroline Masson, the German player who had the best round of the week a 64.

Playing in cool, breezy and sometimes wet conditions, Henderson grabbed the outright lead with an eight8-foot birdie putt on the par-four ninth, her 18th hole of the day. Henderson made her only bogey of the tournament at 11, but rebounded with birdies at 12, 14 and 3 before the late burst.

Henderson, who turns 18 in September, has made $466,818 in nine LPGA Tour tournaments and has the outright 36-hole lead for the third time. LPGA Tour Commissioner Mike Whan denied Henderson’s age petition last year, preventing her from playing Q-school. She earned a spot in the field in Monday qualifying.

Masson had eight birdies, four on each nine, in her second straight bogey-free round after missing the cuts in five of her six previous tournaments.

Candie Kung, Julieta Granada and Jenny Shin were tied for third at nine under. Kung, a four-time LPGA Tour winner, had a 66, Granada shot 69, and Shin 68.

O’Sullivan advances at U.S. Women’s Amateur

Hannah O’Sullivan made a 10-foot par putt on the 18th hole to beat Southern Methodist junior Lindsey McCurdy, 1 up, in the U.S. Women’s Amateur quarterfinals in Portland, Ore.

Two holes down after 10 holes at Portland Golf Club, the 17-year-old O’Sullivan, from Chandler, Arizona, won the next four holes — making three pars and a birdie on the par-four 14th — to take a 2-up lead.

McCurdy, from Liberty Hill, Texas, won the par-4 16th with a par to pull within one, and halved the par-three 17th to keep the match alive. O’Sullivan holed the winning putt after running her 25-foot birdie attempt past the hole on the par-five 18th.

O’Sullivan, also a semifinalist last year, will face 17-year-old Mathilda Cappeliez of France, a 5-and-4 winner over Tennessee sophomore Anna Newell of Tampa, Florida.

In the other quarterfinals, 17-year-old Sierra Brooks of Sorrento, Fla., beat UCLA junior Bronte Law of England, 5 and 3; and 18-year-old UCLA freshman Bethany Wu of Diamond Bar, Calif., topped 16-year-old Mika Liu of Los Angeles, 5 and 4.
