Brother and sister team Lloyd Jefferson and Lois Kaye Go will be trying to keep it in the family. But there will be pressure coming from the outside.

Lois Kaye, former Asian Games team champion member, is protecting a two-shot lead entering the final round of the ladies' competition.

And whether they could keep both the ICTSI Palos Verdes Championships in the House of Go will depend on how the newly turned pro perform Thursday at Rancho Palos Verdes Golf and Country Club.

She posted a 71 for a 143 total, holding off the charge of Chihiro Ikeda whose 72 enabled her to take solo second place for 145.

Laurea Duque is at solo third after a 72 for 147.

Sarah Ababa, last week champion, is tied for fourth with Harmie Constantino at 148, following identical 73s for 148. Florence Bisera occupies sixth place after a 75 for 149.

Myra Legaspi, Marvi Monsalve and Mikha Fortuna are a stroke further at 150 on rounds of 73, 75 and 76, respectively.

Lloyd Jefferson kept Ira Alido at bay after carding a two-under-par 70 for a two-stroke edge halfway through the men's competitions.

He navigated through a roller-coaster backside start of 36 with a strong charge at the front, salvaging four shots in two critical holes and draining two more birdies to claim the solo lead at seven-under 137. This moved him 36 holes away from scoring a breakthrough victory on the Philippine Golf Tour.

Highlighting his round were a scrambling par on the par-5 No. 1 and a lengthy birdie putt on No. 4, which Go described as crucial saves in challenging, hot conditions. Encouraged by his performance, he expressed his determination to maintain his momentum and secure the elusive win over the next two days.

"I hit an OB (out-of-bounds) on No. 1 but eagled it on my second ball for par, and made a long birdie putt on No. 4. That's probably four shots saved," said Lloyd Jefferson, who matched Sean Ramos' 67 to share the opening day honors in the P2 million championship put up by ICTSI Tuesday.
