On the eighth hole of Cameron Young and Xander Schauffele's Four-ball match against Hideki Matsuyama and Ryo Hisatsune on Thursday, Young found himself in a situation we all find ourselves in during weekend team match play games with buddies. Young was pretty much out of the hole after hitting his approach in the water, but he took his drop anyway and chipped his fourth shot to four feet, setting up a bogey putt. His partner, Schauffele, meanwhile, missed the green with his second then chipped it up to eight feet, right on the same line as Young's bogey putt.
After some deliberation and calling in a rules official, Hisatsune told Young to pick up his mark. Normally, in weekend games, your partner would ask you "show me the line." That's actually not allowed, as NBC rules analyst Mark Dusbabek pointed out right after. You are technically allowed to putt out even if the putt has been conceded, except if that putt is going to aid your partner. It's one of those rules we all break in our own money games, but it would actually get you in trouble in a legitimate Four-ball competition. According to Rule 23.6, if you putt out and show your partner the line, your score would count without penalty, put your partner's score would not count for your side.
Schauffele, naturally, missed his eight footer, and the Internationals took the hole with a par.
