GolfWRX Spotted: Callaway Epic Speed Triple Diamond fairway wood

This week the PGA Tour is in New Orleans for the only team event of the PGA Tour season, the Zurich Classic.

Tour trucks are out in full force, and it looks like one Callaway Staffer, Xander Schauffele, will be putting a new prototype CallawayEpic Speed Triple Diamond fairway wood into play—or at least testing it.

We were tipped about the prototype fairway wood thanks to it being Johnny Wunder’s Chef Ticket of the Week, and although we don’t have all the details on what this Triple Diamond head is all about, we can attempt to draw a few conclusions based on some physical observations.

  • The Xander Triple Diamond appears to be smaller from front to back, which naturally will push the center of gravity closer to the clubface—this helps with workability.
  • Although it is harder to decipher, the transition from the hosel to the skirt/sole of the club looks longer and doesn’t transition as fast as the retail model. This has me believing the face of the Triple Diamond is deeper, which also has me concluding the club is shorter from heel to toe.
  • Last but not least, the most obvious is that, unlike the standard Epic Speed, Xander’s (on the left) has two weight ports (like the retail Max model). This gives the tour truck builders the opportunity to quickly tweak the heads and dial in spin.

Whether it will go into play for Xander this week at the Zurich is still up in the air, but we will be keeping a close eye out to see if we spot any other players testing or putting one in play.

Remembering the 2018 Wells Fargo and the Tiger Woods Phase 1 irons



As we prepare for the 2021 rendition of the Wells Fargo Championship at Quail Hollow Golf Club in Charlotte, North Carolina, there is no better time than to look back at some of the modern history of the event, including when Tiger Woods set the equipment world ablaze by showing up with his very first set of TaylorMade irons the TW Phase 1 in 2018.

The TaylorMade TW Phase 1 irons went into Tiger’s bag after almost a year of using the much-discussed TGR Prototype, which were confirmed to have been made by Nike before they closed up shop (but were stamped sans Swoosh or other Nike badging).


We should note that the team at Artisan Golf including the famous man behind the grinding wheel Mike Taylor did help in the prototyping of the Phase 1 irons, which lead to the final creation: the TaylorMade P7TW.

The PH1 set was a collaboration between TaylorMade and Mike Taylor with a new cosmetic design we created. We didn’t want to change any significant performance attributes because the immediate goal was to get TW into a TM iron. We partnered with Mike Taylor to help with the creation of PH1 as well as the learning process required for the development of P7TW. For us, it was a learning experience as TW went through his testing protocol for a new set. Making sure everything was dialed in and felt right.

– Matt Bovee, Taylormade Golf

With all the equipment news, it was a big week and for Tiger. The new irons resulted in a T55 (+2) with the highlight being a 68 on Saturday. As for the winner, it was Jason Day at 12 under. The Australian notched a two-shot win over Aaron Wise and Nick Watney. It was J-Day’s last win to date.

GolfWRX Spotted: Ping i59 irons (exclusive in-hand pictures)



This week, GolfWRX is on-site at the Wells Fargo Championship getting all of the inside equipment scoops from the tour vans, and early this morning we got the scoop of scoops with in-hand pictures of the highly anticipated new Ping i59 irons.

GolfWRX forum: Ping i59 irons – 2021 Wells Fargo Championship

We first spotted these i59’s in the bag of Viktor Hovland a couple of weeks ago from a distance, and now, thanks to in-hand pictures (including some comparison shots) we can take a closer look.




Even with access to taking images, we don’t yet have any details of the technology from Ping, although there are a few things that can be deduced from the images we captured from the Wells Fargo.

GolfWRX forum: Ping i59 irons – 2021 Wells Fargo Championship

  • They are clearly an “i” iron: The name alone gives us a lot of insight into the golfer this iron is targeted towards, and the i-Series has always been a “better players” iron with added forgiveness. The i59s clearly looks the part with a compact profile and medium to thin sole width.
  • It looks hollow: Based on the head geometry combined with the toe screw, I am willing to bet that these new i59 irons ( at least in the longer irons) are hollow.
    Hollow irons aren’t new for Ping but a player’s centric hollow iron is, which is part of the reason I believe Ping has chosen to go a little off-menu with the name—this is not like any iron Ping has released before.

Beyond speculation, we don’t have any further details about a potential release date, but we will follow this story closely. It’s very rare for Ping to release an iron out for tour use without a release date on the horizon, but with 2020’s impact on OEM logistics, it’s anyone’s guess at the moment.
