Thanks to her new putting grip, Brooke Henderson is off to her best start in a major this year.

After adopting a left-hand-low putting stroke in June, the Canadian started the Amundi Evian Championship with a bogey-free, 7-under 64.

Henderson's troubles with her short game for the better two years have prevented her from opening with a round under 70 at one of the five major championships for the first time in a year.

"It feels perfect for getting the significant championship to a strong beginning. To break the top 10 in a major for the first time this year, Henderson, who feels like he hasn't done that this year, said, "It feels good to get one here.

At the Evian Resort Golf Club, Henderson started her round with back-to-back birdies to get things going. The 24-year-old took off after the halfway point, making four birdies in a run of five holes, and recovering from her lone bogey at the par-3 eighth with a final-hole eagle at the par-5 ninth.

"Overall, the day was enjoyable. Henderson, who completed the course in only 26 holes on Thursday, said: "I feel like ball striking, I gave myself a lot of fantastic opportunities, which is always good, and then I was able to make some putts." "Whenever that occurs, you can typically go pretty low."

Henderson had a putting average that rose as high as No. 34 in 2018 and fell to No. 111 in 2021, with an average of more than 30 putts a round.

Henderson transitioned to the new look early this summer after experimenting with various putters and grips the previous two years. At the ShopRite LPGA Classic in the same month, Henderson achieved her first victory in more than a year.

It was a turning point for the Canadian, who had just experienced back-to-back missed cuts.

"I'm not very tech-savvy. Henderson stated of her new putting grip, "I had a fantastic feeling to it. It just significantly boosted my self-confidence. In my opinion, the central issue in putting is simply confidence and feeling good about the putts. I believe it has improved upon several of my stroke's weaknesses, which is good.

The KPMG Women's PGA Championship in 2016 was the site of Henderson's lone major triumph. At the Evian Resort Golf Club, where she has made seven appearances, she has twice been in the top 10 (in 2016 and 2018).

"This golf course may be quite challenging. After her round, Henderson commented, "It plays incredibly difficult. But occasionally, you may gain momentum when you shoot a lot of birdies, which is what happened today. Just maintain the impetus for the remainder of the week, hopefully.
