Whispers from the tour vans at The Open Championship, via our Johnny Wunder’s crack reporting. JW has his finger on the pulse of what’s going on in the world of reps, techs, new builds, and new product. Here are his notes on equipment switches of note from Royal Portrush.

1. Tony Finau had a Ping Blueprint 2-iron built up. The strategy here is self-explanatory: knee-high fastballs.

2. Tiger Woods was seen testing a heavier headed Scotty Cameron proto that is a replica of his famous wand that he’s used to win 14/15 majors. In addition, he also added lead tape to the back of his famous Scotty. The strategy here is to create a heavier head feel which is helpful on slower greens.

3. Do we see Bryson Dechambeau with PXG wedges in his bag?! The rumor is after messing around with a friend’s wedges during a practice round, he liked, he wanted, and he now has. Where this will go from here is anybody’s guess.

5. Jason Day is testing a new TaylorMade Spider X Chalk which would be the first switch he’s made from his Red Spider Tour in a long time. DJ is as per usual testing new putters he was seen with a Spider Copper Mini. What he will land on for the Open is anyone’s guess.

6. Jordan Spieth is now into a set of Titleist T100 irons: 5-9, Project X 6.5 shafts.

Per Titleist…

“While Spieth waited to put the T100’s in the bag until the season’s final major, he is not unfamiliar with the iron. In fact, according to lead Titleist Tour Representative, J.J. VanWezenbeeck, Jordan was clearly the most influential player in the development process.”

“It was over two years ago that Jordan and [Titleist Director of Iron Development] Marni Ines had already started discussing what Jordan was looking for in a next generation iron,” said VanWezenbeeck. “The keys for Jordan were sole, offset, and overall look. As we created early prototypes and discussed specifics with Jordan and other players, we found an opportunity to take everything we learned with the AP2 line and build an entirely new iron. There was an obvious challenge to surpass the most played tour iron in the world.”

“The final T100 prototype was revealed to Jordan and other select players during a Titleist photo shoot at Scioto CC during the week of the Memorial.”

“Jordan immediately commented that the offset and top line was everything he wanted,” said VanWezenbeeck. “As we moved to the tee, Jordan kept commenting to Marni about how the club set up and the look was just what he was looking for. Knowing we succeeded in those categories, now the question became, ‘are you getting the performance of the AP2 line and more, despite being in a sleeker chassis?’ His performance and responses at the hitting session confirmed we succeeded at what we set out to do.”

7. Webb Simpson is also into a set of Titleist 620 MB irons: 5-9, True Temper Dynamic Gold TI X100 shafts.
