GolfWRX Spotted: Titleist TSi4 on USGA Conforming List
After all the excitement caused by the Titleist TSi2 and TSi3 driver and fairway woods, it didn’t take long for another Titleist TSi series driver to pop up on the USGA and R&A conforming club lists, and this time it’s the TSi4.

left-handed driver head from USGA list
Based on the entirety of the information provided in the submission, including the fact that it has been submitted both right and left-handed, leaves us to believe that along with the TSi2, and TSi3, which are currently going through the seeding process on the PGA and Korn Ferry Tours, the TSi4 will also be coming to retail in the near future.
If you remember last year in the spring of 2019, Titleist added the line extension of the TS1 and TS4 drivers to cater to further reaches of the fitting bell curve, for players that needed more launch and spin, and for those that needed further reduction respectively.

The line for the TS4 was simple—the smallest and lowest spinning member of the TS family of drivers. It reduced spin by an average of 300-400 RPM compared to the TS2 and TS3 drivers. All of this while also in a player preferred 430cc package.
To achieve those kinds of dynamics, MOI of the driver’s head has to be sacrificed in favor of creating a low and forward center of gravity to create lower spin. The curious thing with the TSi4 is if Titleist engineers have been able to boost the head size to a full 460 and keep a similar profile or if they have reverted to a sub 460cc design to replicate the TS4’s mass properties and CG location in a new package with new technology to increase ball speed around the head and increase spin robustness.
Time will tell if and when this becomes available at retail, but based on this information, it’s most likely sooner rather than later.

Slab city on the Korn Ferry Tour — Lead Tape Report
This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.
Joel Thelen
Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.
First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.





Mitchell Meissner
Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.

- macedan: “Started with a hand-me-down Golden Bear set from my brother when I was in high school, never really played more than once a year or got into the game until about summer of 2017. First purchased a set of Cleveland CG4’s (I actually really miss this set sometimes, soft & not terribly large for a GI iron), moved into Nike Vapor Fly’s by the end of the year. Those lasted until spring of 18 when I decided I wanted new, so I traded them in for TM Rbladez. Honestly, although I liked the Rbladez, poor decision on my part, I think this was really about the only time so far that after a week or two I was kicking myself for not staying with what I had. Rbladez stayed with me until late last summer when I switched to P790’s and (knock on wood) I am hoping this will be my longest lasting set.”

I hope they stick with the sub 460cc design. I currently have the TS4 and love the smaller head. A 460cc TSi4 would be quite a turn-off for me. Makes no sense also becuase it would be too similar to the TSi3.
