Titleist fires a salvo in the mini driver wars with the new GTS300
Titleist is back with its second mini driver in 18 months, which debuts in tour bags this week with a bigger footprint and a raft of new tech.
Titleist has had a high-profile start to the 2026 season, maintaining a presence in the bags of almost every PGA Tour winner so far this year while also building significant hype around the pending public launch of its new GTS metalwood range.
Now, the brand is taking its next steps into an ever more contentious realm in the equipment space, unveiling the successor to the GT280 Mini Driver that it launched around 18 months ago and announcing that it'll make its debut on professional tours this weekend.
Beyond sounding a bit like a Japanese supercar, the GTS300, as it's called, solidifies the mini driver as a key pillar of Titleist's GTS metalwood offering, which has already seen more than 50 PGA Tour players adopt either a GTS driver or fairway wood. It has also seen Titleist tweak the pint-sized formula of the GT280 somewhat.
As the name suggests, the GTS300 is slightly larger than the GT280, gaining 25cc in overall footprint, retaining a carbon composite crown similar to that used in the previous model for optimum weight dispersion.
This brings with it a higher MOI, and therefore more forgiveness, while maintaining its flexibility to be used as a fairway club, and also brings it into line with the size of mini drivers from the likes of TaylorMade, Cobra and PXG.
"The main goal in development was to make GTS300 a more forgiving mini driver," said Stephanie Luttrell, Titleist’s Senior Director of Metalwood Development. "The increase in volume and shift in CG gave us approximately 15–20% greater inertia. At the same time, we still put a premium on versatility and performance off the turf with this club."
Even so, it's still among the smaller mini drivers out there, with Callaway's Quantum Mini the largest at a full 340cc.
Beyond the expanded footprint, the GTS300 also debuts a new forged L-Cup face, improving performance on low strikes – a boon for players who love to use mini driver off the deck.
“When we originally built GT280, a lot of it was trying to make sure that we were looking for as much performance off the ground as we could,” explained JJ Van Wezenbeeck, Titleist’s Senior Director of Club Promotions.
"Players started saying, ‘hey, I can actually hit this off the ground really well. I'm looking for some more forgiveness.’ And so there was an opportunity for R&D to make the head slightly bigger and increase MOI while still maintaining all the off the ground performance."
It also has has the same flippable forward-rear weight the GT280 had, enabling players to dial in their ball flight either for launch and spin or a more penetrating trajectory.
Titleist also revealed that both Justin Thomas and Cadillac Championship winner Cameron Young assisted in the development and design of the GTS300. Thomas has already put the new club in the bag.
Titleist's NEW GTS300 mini driver will be in golf shops worldwide beginning July 23.
