Watch: Rose's ball hits Schauffele's ball, both go in water

When Xander Schauffele hit his second shot to the par-5 18th, with the WGC-HSBC Champions title hanging in the balance, he anxiously hoped it would STOP. And, stop it did, just behind the putting surface, just short of a severely shaved bank that runs into the water hazard.

Justin Rose’s third shot into No. 18 showed how close Schauffele’s ball came to danger, as Rose’s ball hit Schauffele’s ball and both raced into the drink.

Unbeknownst to some of the Shanghai fans, Schauffele was able to replace his ball without penalty. He ended up two-putting for birdie to get into a playoff with Tony Finau.

Rose, however, took the penalty stroke and made bogey-6 for an even-par 72 and a solo third-place finish.
