Brooks Koepka makes ANOTHER putter switch in a bid to save his PGA Tour season

Brooks Koepka's putting has been the subject of much fascination on the PGA Tour this year.

In his return season since returning from the LIV fold, the American has played relatively well, but has been consistently let down by sub-par work on the greens, cycling through a number of different putters and reportedly even breaking one following the Truist Championship earlier in the season.

It did briefly appear that he had turned a corner after placing a new Scotty Cameron in the bag in the lead-up to the CJ Cup Byron Nelson, putting lights out en route to a bogey-free opening round of 63. 

But his performance since then has been middling, and he ranks 116th on in putting for the season.

Koepka's ability to get it together with the flat stick is now truly in its crunch moment.

Despite making 10 of 15 cuts so far this year, needs a solo top four finish at this weekend's Wyndham Championship to put himself in the PGA Tour play-offs. 

Failing that, Koepka's return to the very highest level of professional golf may go down as a bit of a damp squib.

As such, Koepka has once again made a switch at the short end of his bag in the hunt for renewed fortunes on the greens. 

He has worked with Scotty Cameron on a new variant of the Phantom 3 mallet, equipped this time with a Teryllium insert.

Teryllium insert putters are a bit of a Scotty Cameron hallmark, with plenty of the brand's loyalist using one at some time or another. It's a material noted for its softer feel and distinct auditory feedback. 

Tiger Woods most famously won the 1997 Masters using a Teryllium-faced Newport, and Koepka himself has a long history of using the material in his putters, including those that he used to win most of his major victories.
