Angel Yin rammed in a 30-foot par putt on her opening hole, setting the tone for a day of big putts and 3-under 69 that gave her a two-shot lead Friday in the CME Group Tour Championship and the chase for the 4 million prize.
Very clear in her rearview mirror was Nelly Korda.
Korda, coming off her seventh win of the season last week, opened with a 72 and was eight shots behind. She found a simple swing thought after the round and was back to her old self with a 66 that cut the deficit in half with 36 holes left to play.
"Golf is just crazy," Korda said. "You go from playing so well last week to not being able to find the center of the clubface yesterday. Always humbles you, but what's that you love so much about it. Went to the range after my round yesterday. Tried to find a different feel. Felt a little better out there today, and hopefully I can keep progressing."
Yin followed that 30-foot par putt with a 40-foot birdie putt on the next hole. She also holed a birdie putt from about 35 feet on the 11th hole that put her in the lead for good.
