A thrilling finish from the University of Oklahoma's Ryder Cowan ensured he shares the US Open low amateur honors with Jackson Koivun, who turns professional on Monday.
The pair were among five amateurs to make the cut at Shinnecock Hills. After Koivun carded a two-under final round of 68, including a birdie at the 18th, to finish on five over, it was over to Cowan to determine the destination of the gold medal.
