New Titleist TSi2 and TSi3 Drivers and Fairways woods for 2021 spotted on the PGA Tour this week. After a great deal of speculation around how the new Titleist woods line would continue to build on the great strides the TS series took, we now have official visual confirmation.

The Titleist TSi Series will be kicked off with TSi3 and TSi2 models for late 2020 into 2021 in both drivers and fairway woods, and it is not a stretch to believe that they will fall closely in line with previous TS2 and TS3 segmentation.

The new Titleist’s TSi drivers and fairway woods are here! And by “here,” I mean we have preliminary images as found on the USGA conforming drivers list. (USGA images below, featured image c/o Titleist)

We have reached out to Titleist and have no official comment yet, but based on the images and our knowledge of previous models, we can draw some conclusions based on the visual elements and markings—including the fact that the new TSi3 will have an external sliding weight track—the first time a sliding weight has been built into a Titleist wood.

Titleist TSi Series (speculated) technology

Although we can only see the sole of the new drivers, there are some design points that allow us to make strong assumptions on the new products, including the adjustable tip being used is the same as in previous generations.

Titleist TSi2 Driver

The TS2 driver has been a big hit for golfers whose natural swing dynamics create mid-to-lower spin, and the TSi2 looks to continue to fit into this category with a single adjustable weight in the rear of the club.

The big tell appears to be a lot of mass positioned low and in the middle of the sole – based on the graphics/visual technology represented in the available images. I would expect the next steps to be a lighter and/or stiffer crown and an improved shape to boost MOI—potentially making the “i” in “TSi” stand for “improved.”

The last part of the ‘improvement” is most likely a new face design to help increase ball speeds on mishits, which leads me down another speculation path: The “i” could stand for “intelligent,” and Titleist will be selling an AI (artificial intelligence) story, but based on Callaway’s success in that department, I highly doubt it.

TSi2 Fairway wood

The TSi2 fairway appears to fall in with the TSi2 driver with centralized mass and adjustable rear weight. Since fairway wood technology is being advanced as quickly as drivers, I would expect to see an improved face paired with an overall lighter frame.

As for continued technology, the woods will have ARC (Active Recoil Channel), and what looks to be the same hosel sleeve.

Titleist TSi3 Driver

The TSi3 looks to be the big kahuna, with Titleist pulling out all the stops by adding both an adjustable and sliding rear weight.

The 2018 TS3 was a driver designed to help lower spin and help players fine-tune ball flight with adjustable CG. The TSi3 is taking it further by moving that adjustability to the perimeter of the head to create greater CG movement and higher MOI. We have seen this very rear-positioned mass on a number of recent releases, including Cobra, TaylorMade, and the upcoming new Ping G425.

The reason we are seeing these similar design trends is thanks to physics and finite element analysis, which is “a computerized method for predicting how a product reacts to real-world forces, vibration, heat, fluid flow, and other physical effects.” Golf club engineers are smart people, and they are always pulling levelers in an attempt to maximize a club’s potential based on available technology and manufacturing methods. It’s the same reason we are seeing super-car designs in relation to aerodynamics become more homogenized because of the goal to achieve aerodynamic perfection.

*Update: Photos of the TSi3 driver from Ian Poulter on Instagram

Like with the aforementioned TSi2 I would expect to hear more about weight savings from the removed weight housing of the TS3, which will boost the TSi3 MOI along with an updated face designed to maximize ball speed.

The last note is on the overall shape. Compared to the 2018 TS3, the new TSi3 looks to be smaller front to back and shorter heel to toe. In a way, its shape makes it look like the previous TS3 and TS4 had a bit of a baby and it could also mean that Titleist has no plans to possibly expand the line if they have achieved in getting the spin low enough in the TSi3. Obviously, that is a big bit of speculation, but one we should consider under the circumstances.

Titleist TSi3 Fairway Wood

The visual technology seems pretty self-explanatory for the TSi3 fairway woods with a compact shape paired with an adjustable forward weight to help control launch and lower spin. The weight looks BIG, and this most likely means engineers have shaved a lot of mass around the head to help centralize mass in the sole.

Fairway woods already go a very long way, and if Titleist has figured out a way to make their new ones go farther and straighter, then that’s a winning combination.

Like the TSi3 fairway, the patented ARC is behind the face and should help with lower face strikes too.

Conclusion

This release from Titleist is going to be interesting to follow since the entire TS series from Titleist was such a huge success. We don’t have information on the retail dates, but Titleist has generally stuck to a late fall schedule after the tour seeding process initially conducted on the PGA Tour, so with these now on the USGA list we can expect tour seeding to begin shortly.
