Michael Brennan Wins With "Mystery" Titleist 3-Wood
Michael Brennan secured a victory at the Wyndham Championship with the help of a mystery Titleist 3-wood that nobody wants to talk about.
Michael Brennen put on a stellar performance this week at the Wyndham Championship with rounds of 66, 65, 63, and 64 to earn his second PGA TOUR title, and he did it with power and touch.
Not only was he ranked 3rd in strokes gained off the tee, but he was also second in putting with a combined +8.958 for the week - well above his season average, which equates to -0.068 per four-round event.
But beyond his putter and driver, there was one more club in Michael's bag that stands out, and has stood out for other players this year on the PGA Tour too, and that is the Mystery Titleist GTS 3-wood that simply goes by the name of GTS prototype.
What separates the prototype from the rest of the currently available at retail GTS fairway woods it's its use of single central forward weight compared to the heel and toe weighting systems found in the GTS3 and GTS2. The one weight also makes it different from the previous surprise hit GT1 Tour model 3-wood that utilized a front and back weight to help players get dialed in.
Titleist GTS3 Fairway Wood
For players with a more downward attack angle, GTS3 fairway features a deeper face height that promotes consistent center-face contact.

Speaking of that previous GT1 Tour 3-wood, it was a mid-cycle release that also started as a tour-only prototype, but eventually made its way to retail, which is something we could see from this club. As for the details on the GT1 Tour, I'll let Titleist’s Senior Director of Club Promotions, JJ Van Wezenbeeck explain the origins of the design.
During GT1 fairway testing, we found some TOUR players really loved the shaping and face height, but we knew that many of them would need a little less loft and lower CG for a stronger flight. Tom Bennett [Principal Product Manager, Titleist Metalwood R&D] and the R&D team were able to give us a product in GT1 3TOUR that gave us all the benefits of the GT1 shaping while lowering spin to a more optimal window for those players.

The GT1 3Tour generates high-launching, ultra-stable performance with a stronger “Tour Loft” design to keep spin in the optimal range.

One of the biggest misconceptions around long game spin is that tour players use clubs that generate ultra-low spin, when in fact that's not quite the case. Instead, the main goal is to find clubs that fit a particular spin window based on their swing dynamics into the golf ball to help produce consistent distance results. There is no point in having a club like a 3-wood that goes 270 on one swing and 295 on another if the spin becomes too variable.

And this is where we bring it all back.
What The Heck Is It?
If the new GTS prototype isnt a GTS2 or 3 and based on the single weight setup its not likely a GTS1 (which if product cycles go the way they has been going will come out late fall or early next spring) than what could this prototype really be?
I think it's a GTS4 fairway wood.
Considering Titleist almost scrapped the GTS4 driver concept since the previous GT4 was such a niche product, before making it (GTS4) a 460cc head design and seeing tour (and general public) usage jump significantly, I think this new option adds to the lineup.
This prototype fairway wood is shallow enough to use of the deck and offers a clear separation from Titleist's new GTS300 mini driver which offers added forgiveness off the tee. And, for faster players like Brennan who have used the GT1 Tour 3-wood in the past, it only makes logic sense that (with the single forward weight position) Titleist engineers have built a shallower forward center of gravity fairway wood designed to keep spin in a tight window.
The only questions left to ask now is if this prediction correct, and if so, when can we get our hands on one too?
