There is an old saying that “is not the arrow, it is the arrow” for gear gears that try to fix everything wrong with their games making a change of equipment.
In the case of Jenny ShinIt turns out that it was really the arrow.
Shin had been fighting in Tee this season, at least relatively, as her 73 percent accuracy is declining from the average of her 78 percent career. While this may not sound too much, at the pros level, this may be the difference between holding or losing your card.
But the shin finally reached its end this week past in PGA Championship for KPMG women. Shin, who has one of the most sincere presence of social media in women’s golf, said in a series of posts in X that she revealed that she had been playing with a driver who was four more heavy rocking points than it should have been.
This Tuesday, I discovered that I was using a driver that was 4 rocking weights heavier than I used my whole career

That is why this made such a difference to her and what it can say about you.
Where everything started
Last summer, the rapid driver of the epic speed of the Callaway Shinwhich she had used for four seasons, failed a conformity test – Yes, Women’s drivers are also tested – In the Open Women’s Championship.
LPGA leaders do not Jump CT boundaries past as often as they make in PGA TourBut as long as Shin used that driver and how often she probably hit her in the same exact place, it’s not surprising that she was finally heated.
At her Twitter yarn, she explained that she did with a spare driver, but didn’t need much for Golf links and ended up ending T17. The search for a replacement, however, was tougher.
“Since then, I couldn’t find a driver who could repeat my original driver,” she said on X. “in a way just didn’t click. Of course, my accuracy went down and I continued to lose the right roads. Then January, I managed to find one I could hit somewhat right.
“Miss was right, but felt manageable. My gir started to fall sharply compared to last year due to lost roads. I started to aim for the left and then Miss My Miss Becom (sic).”
With the decline of approximately five percent of Shin’s accuracy, she also saw her greens in the percentage of adjustment falling with about the same difference.
Then in April, she noticed that her swinging road was going out more, with all her clubs, and she said she cost 8-10 yards of distance.
I always had a very neutral routing route and I control my religious shake on the camera. In the video it looked good, but in April, my club path was -3.4 ~ -4.8 with 6 and my face on the trail was +4.
I lost about 8-10 yards in the distance and was confused how he got there– Jenny Shin (@jennyshin_lpga) June 21 2025
She also saw herself last week in the video and noticed that the vertical movement of her body while swinging was “out of control”.
DISCLOSURE
This week in the KPMG women’s PGA championship, Shin was falling balls in the range on Monday, she said, trying to correct the right miss that she was scared could penalize her on the Fields Ranch East.
This is when a reps of Srixon Tour she knew and noticed her and stopped asking if she needed anything.
“I’m desperate, can you build me a driver who is D0?” Shin asked the representative, referring to her favorite weight.
We then discovered that the driver I used was in D4
No wonder I can’t flatten my face. It all made sense after that.

Most of the benefits, even those who are not gearboards, are well known for their specifications so that they can get a replacement or backup whenever they need it. Shin’s previous gamer was D0 and so was the driver she was currently playing.
Or so she thought.
“We discovered that the driver I used was in D4,” Shin wrote.
Why does it matter
Driver Shin was using was four points of shaky weights heavier than it was specified for it. This ends by being approximately an 8 grams of head weight (or something else, depending on any weight in the syllable).
It does not sound too much, but Shin was definitely very subconsciously sensitive to weight change and it made her change her swing.
So while there was nothing technically wrong with the club, due to the heavier weight of the swing, she reacted by swinging more on the inside, causing the right miss.
Getting clubs suitable for you can be so much that you get a club that makes the ball do what you want, as you are getting a club doing you Do what you want. While everything else could have been the same as the driver as a previous version, the extra weight was making her swing react in a way she didn’t like.
That is why it is not only important for you for your clubs to adapt, but also to verify the specifications that match what is thought to be. Your local golf store will usually have all the tools needed to do so.

These types of weight discrepancies are rare in professional golf, but they can happen. Matt Fitzpatrick passed a similar experience Last season when he discovered that he left a back weight under his driver’s control.
Score
Shin had a new driver Srixon ZXI with a Mitsubishi RB RB shaft built for her and immediately put her in the game last week in women’s PGA.
While Shin did not see a great deal in accuracy or distance in a difficult group Fields Ranch East Setup, she put on one of her best shows hit with the ball of the year, ending in 6th place in strokes: Access (1.35) on her way to a T12 finish, the second best of the year.
That’s a wild week for me so far. The emotional journey of the roll
has been true. Having a completely different oscillation in a 24 -hour issue and seeing evidence and building back trust has been an incredible emotion

While it may not have been the driver who was directly responsible, having one who was the right weight of the shake allowed her to recover her sensation with the rest of her game and she appeared with her iron game.
She immediately blamed her swing for her inconsistencies throughout the season, but as it turns out, she was too fast to exclude her clubs.
