ONEIDA, Wis. — The man, part of the same generation as President Trump, approached the American Cristie Kerr, a two-time major winner and former women’s world No. 1, in front of the clubhouse at Thornberry Creek, where the L.P.G.A. last week held its first event in metropolitan Green Bay.

He told Kerr that it was his first time watching in person some of the best female golfers in the world, and that his view of them had been forever changed by what he saw.

“You girls look heavier on TV,” he said.

The event in Wisconsin served as the final tuneup for the 72nd United States Women’s Open, which figures to attract more attention than the one 10 years ago at Pine Needles in Southern Pines, N.C., when Kerr won her first major title. But the attention will be because of the tournament’s location rather than its deep list of contenders.

The championship is being held at Trump National Golf Club in Bedminster, N.J., the property that Trump has turned into his summer retreat.
