Justin Thomas WITB (16th February, 2025) - What's In The Bag? Genesis Open at Torrey Pines South Course

Justin sticks with Titleist’s GT2 driver, but there’s a subtle shaft change. He’s moved from a Mitsubishi Diamana ZF 60TX to a Mitsubishi Diamana Prototype shaft, likely in search of slightly different launch and feel characteristics.

February 16, 2025

Who is Justin Thomas and WITB for 2025?

Justin Thomas is one of those guys who could probably hit a golf ball through a hurricane and still walk up to the green complaining about his putting. A two-time major champion and former world No. 1, JT has been one of the most consistent stars on the PGA Tour over the past decade, blending effortless ball-striking with an attitude that oscillates between fiery competitor and laid-back goofball.

Born in Louisville, Kentucky, in 1993, Thomas was destined for the pro game early on. He played college golf at Alabama (Roll Tide, of course) and quickly became one of the most decorated amateurs in the country. Turning pro in 2013, he wasted little time making his mark, securing his first PGA Tour victory at the CIMB Classic in 2015. But it was his monster 2017 season that truly cemented his place among golf’s elite—winning five times, including his first major at the PGA Championship, and taking home the FedEx Cup title.

Since then, he's racked up 17 PGA Tour victories, added another major in 2022 at the PGA Championship, and has been a staple on Ryder Cup and Presidents Cup teams. While his 2023-2024 stretch hasn’t been his most dominant, JT remains a must-watch player every time he tees it up. And as of Sunday, he’s sitting at T8 (-3) heading into the final round of the Genesis Open—right in position for a late charge.

Justin Thomas' 2025 WITB: Small Tweaks, Same Firepower

While some pros overhaul their bag every season, JT takes a more "if it ain’t broke, don’t fix it" approach. His 2025 setup isn’t drastically different from last year’s, but there are a few key refinements worth noting.

Driver: Titleist GT2 9° with a Mitsubishi Diamana Prototype shaft

Justin sticks with Titleist’s GT2 driver, but there’s a subtle shaft change. He’s moved from a Mitsubishi Diamana ZF 60TX to a Mitsubishi Diamana Prototype shaft, likely in search of slightly different launch and feel characteristics. Given JT’s ability to work the ball both ways, expect him to shape some beauties down Riviera’s tight fairways today.

3 Wood: Titleist TS3 15° with a Mitsubishi Tensei AV Raw Blue 85 TX shaft

No surprises here—Thomas continues to trust the TS3 3-wood, which has been in his bag for years. The Tensei AV Raw Blue 85 TX shaft provides plenty of stability while allowing him to launch high bombs off the deck.

5 Wood: Titleist 915 Fd (18° @19.5) with a Fujikura Motore Speeder VC 9.2 X shaft

JT’s 915 Fd fairway wood is almost a decade old, yet he refuses to give it up. The Motore Speeder VC 9.2 X shaft remains a rare gem, providing an incredible combination of control and ball speed. When you’re one of the best iron players in the world, sometimes you just need a club that gets you into your scoring zones consistently—this is it.

Irons: Titleist T200 (4i), Titleist T100 (5i), Titleist 621.JT (5i-9i) with True Temper Dynamic Gold Tour Issue X100 shafts

Thomas continues with his custom Titleist 621.JT blades (built specifically for him), but he mixes in a T200 4-iron and T100 5-iron for extra forgiveness in the long irons. With Riviera’s tight, Kikuyu-lined fairways, his precise iron play is a major weapon this week.

Wedges: Titleist Vokey Design SM10 (46°-10F @47.5, 52°-12F, 56°-14F @57), Titleist Vokey Design WedgeWorks (60°-K)*

A staple of JT’s bag, his Vokey wedge setup remains unchanged aside from slight loft adjustments. His 60° K-grind lob wedge continues to be a signature club, offering soft hands and aggressive spin control around the greens.

Wedge Shafts: True Temper Dynamic Gold Tour Issue X100 (46°) and True Temper Dynamic Gold Tour Issue S400 (52°-60°)

Thomas prefers a stiffer shaft in his gap wedge (X100) for better full-shot control, while moving to S400s in his 52-60° wedges for added feel and versatility on delicate shots.

Putter: Scotty Cameron Phantom X 5.5 Tour Prototype with a SuperStroke Zenergy Pistol Tour grip

Justin Thomas and Scotty Cameron mallets go together like peanut butter and jelly. He’s rocking the Phantom X 5.5 Tour Proto, featuring a compact shape that enhances alignment without the bulkiness of larger mallet putters. His SuperStroke grip helps with stability under pressure, perfect for Sunday’s final round.

Ball & Grips: Titleist Pro V1x with Golf Pride Tour Velvet Cord grips

No surprises here. JT remains locked into his Pro V1x, trusting the spin, control, and feel he’s relied on for years.

Comparing 2025 to 2024: What’s Changed?

Unlike some gear-heads who swap out clubs faster than they change socks, JT keeps his changes minimal.

The biggest tweaks?

  • Driver Shaft: Moving to a Mitsubishi Diamana Prototype, likely fine-tuning launch and spin characteristics.

  • Loft Adjustments in Wedges: His 46° now plays at 47.5°, his 56° plays at 57°, allowing better distance gapping.

  • Putter Grip Change: Slight shift in putter feel with SuperStroke Zenergy Pistol Tour instead of his previous grip.

Essentially, JT is refining rather than reinventing—and with his ball-striking ability, small changes could make a huge difference in his 2025 performance.

Final Thoughts: Can JT Make a Sunday Charge at Torrey Pines?

Sitting at T8 (-3) heading into Sunday’s final round at the Genesis Open, Thomas has a real chance to move up the leaderboard. Riviera’s firm, fast conditions favor elite ball-strikers, and few control their irons better than JT. If he gets the putter rolling, expect him to contend late.

Will he win today? Maybe. But one thing’s for sure—his WITB setup is dialed, and 2025 looks promising for JT.
