Golf fans have been left baffled by Hideki Matsuyama's unique putting drill at the WGC-Match Play event in Texas.
The drill involved a quarter being placed on Matsuyama's putter and it appeared the Japanese star was attempting to stop the coin from falling off. Even the commentators were fascinated by the drill.
One remarked: "How about that? Balancing a quarter on top of the putter. You have the tee behind so that's going to force the putter up a little bit."
And fans on social media were quick to question the logic behind Matsuyama's drill, with one writing: "What is this drill supposed to help/teach?"
Another added: "How to overthink things 101". A third branded it a "pointless waste of time", while a fourth joked it was "common cents if you ask me".
"This is absurd," added another. Matsuyama faced off against Kevin Kisner in round one of the Match Play event and triumphed 1up, before losing to Justin Suh.
It comes after Matsuyama secured a career best finish in the prestigious Players Championship earlier this month, finishing fifth and banking £834,000 in prize money.
"I think I played well but I definitely could have done better coming in over the last four or five holes," he admitted after the event. "The fact I hit some great shots and great putts will be something I can take with me moving forward.
"I will also look back on the last five holes where I struggled and think about areas I can improve from that." Scottie Scheffler ultimately went on to win the event.
