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."
