ジェイソン・デイのクラブ革命：PGAツアー復帰の秘密を明かす
Imagine completely reinventing your golf game after a break. That’s exactly what Jason Day did. And the results are raising eyebrows. After a two-month hiatus, Jason Day’s return at the Bank of Utah Championship wasn’t just a comeback. It was a full-blown equipment revolution. The former world number one and 13time PGA Tour winner used his time off to dissect his game and overhaul his gear, leading to some seriously interesting choices. Day showed up in Ivans, Utah, sporting a bag filled with brand new prototype irons, updated shafts, fresh grips, and even a new hybrid. He managed a tidy 3 under 68 in the first round at Black Desert Resort, hitting 12 of 14 fairways. Despite all the changes, Day only had 13 clubs in the bag. But here’s where it gets controversial. Why 13 instead of the allowed 14? Day himself admitted his iron play hadn’t been up to par during the season. I hadn’t been hitting my irons grade at all, he explained after his round. This prompted a conversation with his coach Colin Swatton, leading to a deep dive into potential equipment solutions. While Day has a history of experimenting with different iron styles, he’s used both blade and cavity back designs from Tailor Made and Ping. The new prototypes he unveiled at the Bank of Utah Championship represent a significant departure. These weren’t just minor tweaks. They were a bold step in a new direction. These aren’t your average irons. Day is now using a set of 3D printed Avida golf irons co-designed by himself. These irons incorporate a curved face technology reminiscent of what Bryson dashambo utilized during his US Open victory at Pinehurst number two. As an equipment free agent, Day is on a quest to find the best of the best and he and Swaten stumbled across Avda Golf. I just told my coach just have a chat to the guys, see what they think, Day recounted. He got off the phone and called me and he goes, “Man, in all the years I’ve been doing this, I’ve never come across the guys the way they explained everything.” After collaborating with a Voda Golf and developing several 3D printed models, Day’s irons now feature a progressive face curvature. This design aims to minimize sid spin on off-center hits by counteracting the gear effect. PGA Tour live host Lisa Cornwell reported that Day found the underlying technology phenomenal and observed an immediate tightening of his shot dispersion. This means his shots were landing closer together even on mits and this is the part most people miss. While Desambo uses the same shaft length for each iron, Day has opted for standard varying shaft lengths. He’s also planning future modifications after this week. We’re obviously going to get back together and see what needs to kind of be improved. Day stated, I think currently right now, I would like to see a little bit, a tiny bit more offset, try and get a little bit more turn. If that has a little bit more offset, it will actually elevate the ball a little bit more in the air, which would be nice. In addition to the irons, Day has switched to JumboMax JMX Zen Light grips and KBS graphite shafts. He noted that the transition from the heavier dynamic gold X7 136 g shaft to the lighter KBS TGI Tour Graphite 110 g shaft is definitely easier on the body. This could be a significant factor in preserving his energy and reducing fatigue during tournaments. The theory I think I have the same profile shaft from 60° all the way up to driver. Day explained, “A goal is to be able to swing. Just pretty much have one swing, like whatever ball flight you want, whether that’s a draw or a fade. For me, it’s a draw to go up there and hit a draw and pretty much put the same swing on it, and hopefully it produces the same shot over and over again.” Despite all these changes, Day confessed to playing with only 13 clubs, as he’s still dialing in the yardages with his longer clubs, specifically the new Callaway Apex UW Hybrid. is currently in a testing phase to fine-tune the gapping in spin rates. Having secured signature event status for 2026 after a 41st place finish in the FedEx Cup, Day is using this fall season as an opportunity to experiment and aim for his first victory since the CJ Cup Byron Nelson in 2023. Day did mention wishing he had that 14th club on the par five ninth hole where he finished with a bogey. So, keep an eye out to see if he adds that extra club in his bag for Friday’s round. What do you think of Day’s bold equipment changes? Is it a smart move to experiment so drastically, or is he risking disrupting his game? Do you believe more players will start using 3D printed irons in the future? Share your thoughts in the comments below.
