Watch: Pieters snaps putter over knee after making quadruple bogey

Thomas Pieters is known for showing emotions at the expense of his golf clubs. This time, while playing in the Omega European Masters in Switzerland, his putter took a beating after making a nine on a par 5.

Perhaps Pieters is still reeling from being left off the European Ryder Cup team. Either way, he'll need a new flatstick.

Earlier this season, the Belgian used his neck to break a club. Who knows what body part he will use next.
