First came the tears when Nelly Korda hugged her older sister and didn’t want to let go. That was followed by the spray of champagne on the 18th green to celebrate a day that will be hard for her to top even at age 22.

With one round, she became a major champion for the first time and reached No. 1 in the world.

“Is this week even real?” Korda said. “It’s amazing.”

Just like her performance Sunday in the KPMG Women’s PGA Championship.

Korda powered her way to a pair of eagles that wore down Lizette Salas at Atlanta Athletic Club and put an American atop the world ranking for the first time in seven years.

Korda nearly holed out with a 7-wood from 243 yards for a tap-in eagle. She seized control by using her length from that graceful swing, leaving her a 6-iron into the par-5 12th hole that narrowly cleared the water and set up an 8-foot eagle putt.

The final stroke was a 15-foot par putt for a 4-under 68 and a three-shot victory over Salas.
