Brooks Koepka WITB (13th June, 2025) - What's In The Bag? The US Open @ Oakmont Golf and Country Club

Brooks has gone full tilt into the new Titleist GT3, dialing it down to a 10° rocket launcher with one of the smoothest low-spin profiles on tour.

Ball: Srixon Z-Star Diamond

Grips: Golf Pride Tour Velvet Cord Midsize

WITB: Brooks Koepka – 2025 U.S. Open at Oakmont (Currently T2 at -3)

“You don’t win five majors by accident.” That’s a line we’ve been rehearsing for Brooks Koepka for a few years now. But as he stares down the savage, soul-mangling grind of Oakmont in hot pursuit of No. 6, the phrase is starting to feel less like a compliment and more like a warning. Because when Brooks is in the hunt—especially at a U.S. Open—the leaderboard starts to look less like a contest and more like a hit list.

Currently tied for second at 3-under, Koepka is doing what Koepka does: playing surgical, emotionless, big-boy golf while everyone else triple-bogeys their way into a PTSD support group.

Oakmont, for the uninitiated, is golf’s version of a haunted house—but with faster greens and more emotional trauma. The fairways are narrower than a TikTok influencer’s attention span, the rough is ankle-snappingly thick, and the greens? Let’s just say if you’re not bringing top-shelf touch, you’ll be putting it into Pittsburgh.

So how is Koepka keeping his cool while others melt into the Pennsylvania turf? Let’s take a look inside his murder weapon of choice: the bag.

Driver: Titleist GT3 10° with Mitsubishi Diamana D Limited 60TX

Call it understated aggression.

Brooks has gone full tilt into the new Titleist GT3, dialing it down to a 10° rocket launcher with one of the smoothest low-spin profiles on tour. It’s the kind of club that doesn’t scream “look at me,” but if you’re in the fairway behind him, you can’t help but look at where his ball landed—usually 25 yards ahead and dead center.

Paired with the Mitsubishi Diamana D Limited 60TX, he’s prioritizing stability and low launch. That’s how you beat Oakmont: eliminate variables off the tee, because if you’re in the rough, the hole might as well be a black hole. The 60TX shaft keeps spin tight, ball flight piercing, and hands unbothered.

And yes—this setup is a departure from his past flirtations with TaylorMade drivers. The switch to Titleist this season seems to be about trust, feel, and maybe a little bit of passive-aggressive shade toward the OEM world. Classic Koepka.

3 Wood: TaylorMade M2 Tour HL 16.5° with Mitsubishi Diamana D+ 80TX

We’ll say it louder for the gear nerds in the back: The M2 Tour HL is from 2017. That’s right—Koepka is rolling with a club old enough to have voted in two U.S. elections.

This 16.5° high-launch head still holds a place in his heart—and his yardages. It’s a unicorn: hot off the face, just enough spin to stick, and weirdly forgiving. Pairing it with the Mitsubishi Diamana D+ 80TX shaft, he gets launch without chaos.

This is Brooks’ fairway finder, second-shot sniper, and emergency parachute when the driver’s misbehaving. And again—it’s a testament to the Koepka code: if it works, don’t fix it. Just destroy fields with it until the grooves wear out.

Utility: Nike Vapor Pro 3-Iron with Fujikura Pro Tour Spec 95X

How do you know someone was once on Nike’s staff? They’re still gaming a Nike iron.

This 3-iron is more than a nostalgia piece. It’s a scalpel. Whether he’s punching low bullets under Oakmont’s crosswinds or launching green-seeking missiles from 240 out, the Vapor Pro is dialed for one thing: control.

The Fujikura Pro Tour Spec 95X shaft stiffens the whole profile to match Koepka’s signature tempo. It’s a launcher for him—but a punishment stick for anyone else with less-than-Tour-level speed and accuracy.

Irons: Srixon ZX7 Mk II (4-9), True Temper Dynamic Gold Tour Issue X100

Srixon’s ZX7 Mk II irons are Brooks’ current enablers for his control freak tendencies. These irons aren’t built for forgiveness. They’re built for obedience. At Oakmont, where greens are firmer than concrete and smaller than your hopes and dreams, approach precision isn’t optional—it’s mandatory.

The ZX7 Mk IIs give him a consistent launch, workable trajectory, and a piercing ball flight to knife through Oakmont’s swirling air. The True Temper DG Tour Issue X100s are heavy, stout, and lethal—basically a Koepka autobiography in shaft form.

Wedges: Cleveland RTZ Tour Rack Raw – 46° (10M), 52° (10M), 56° (10M), 60° (6L)

Shafts: X100 (46°), S400 (52°-60°)

Koepka’s wedge game is a masterclass in nuance, and his setup shows it.

He opts for four wedges, all raw-finished Cleveland RTX Tour Racks, which age like bourbon—grippy, grimy, and effective. The 46° wedge (his ‘pitching’ wedge) still uses the iron shaft for seamless transition, but from 52° onward, it’s S400s all the way for that added touch and tempo control.

Oakmont’s firm greens demand flighted wedges that spin without ballooning, and the 10M grind helps him manipulate loft while maintaining bounce through the turf. The 60° with the 6L grind is a specialist—low bounce, maximum creativity, and designed for those terrifying tight lies around Oakmont’s death-trap pin locations.

Putter: Scotty Cameron Teryllium Tour Newport 2 Circle T

It wouldn’t be a Koepka bag without a timeless blade that looks like it should come with a security clearance. The Teryllium Tour Newport 2 Circle T is all about feel—something Brooks craves when greens run at 14+ on the stimp and every putt feels like you’re trying to stop a marble on a sheet of glass.

The Teryllium insert gives it a soft, buttery response even on Oakmont’s concrete surfaces. It’s not flashy, but it doesn’t need to be. It just needs to make putts—which, so far, it absolutely is.

Ball: Srixon Z-Star Diamond

This ball is criminally underrated—but not in Brooks’ world. The Z-Star Diamond offers a bit more spin on approach shots than your standard Z-Star and sits between the Z-Star XV and the original in terms of compression.

It’s ideal for a ball striker who wants to absolutely nuke it off the tee, but still feather in wedges with tour-level control. It also holds its line beautifully in wind—which matters when you're playing Oakmont, where gusts can literally turn a good round into a group therapy session.

Grips: Golf Pride Tour Velvet Cord Midsize

Koepka’s grip of choice is basically the Tour standard for guys with big hands and bigger swings. The Tour Velvet Cord Midsize gives just the right mix of tackiness and feedback, with enough size to prevent any handsy panic swings—particularly crucial when you’re standing over a 220-yard par 3 with 4-over in your rearview mirror.

Final Thoughts: Brooks v Oakmont – Who Blinks First?

We said it at the top and we’ll say it again: you don’t win five majors by accident. Koepka lives for this stuff. Fast greens, impossible lies, thick rough, and Sunday pressure? That’s his love language.

At 3-under heading into the weekend, he’s lurking with bad intentions. His gear setup—while a little Frankensteinian—is a perfect blend of vintage trust and modern precision. Every stick in the bag has a job, and every job is tailored to the type of golf Oakmont demands: brutally effective.

So what’s next? If history tells us anything, it’s this: when Brooks is on the board at a U.S. Open, somebody else is usually holding the silver medal.
