Much transpired at Augusta National’s 15th hole for Si Woo Kim on Friday afternoon. By that point, Kim, a 25-year-old from South Korea, was tied for fifth and in contention at the Masters.

But that’s also where Kim had to trade out his putter on the greens for his 3-wood. When Kim slammed the flatstick head-first into the ground in anger next to the 15th green, it broke. That meant he could no longer use the putter to finish his round, and out came the 3-wood.

Remarkably, Kim made par at the par-5 15th. He threw his golf ball in the water anyway.

Asked what caused him to slam his putter and ultimately break it, Kim had this to say: “Just frustration, like last, like 14, 15 chip. Just that’s not on purpose, but it was broken, yeah.”

At No. 16, he nearly made a left-to-right breaker for birdie with the metalwood. He walked away with par there instead.

Kim managed to par out with the 3-wood in hand, though he had a decent look at birdie from about 13 feet on the par-4 18th. His 3-under 69 left him at 4 under for the tournament, three shots behind Justin Rose and tied for sixth.

Kim’s choice of replacement “putter” sparked the question: What club is most useful in the event that a player breaks his putter mid-round?

Post-round, Kim stood by his choice.

“I think sand wedge more harder and hard to spin control, especially this fast green, yeah,” he said.
