Jackson Koivun said his rapid rise stunned him after he helped the United States win the Presidents Cup at Medinah on Sunday, beating Si-woo Kim in singles. The U.S. came back from a three-point deficit as the Internationals won just two of 12 matches.
The 21-year-old was the only unbeaten player across both teams. He said the event showed him he could compete at that level and thanked the captains for trusting him to play in three of the five matches.
Captain Brandt Snedeker selected Koivun despite his not advancing beyond the first FedEx Cup playoff event. Koivun had won the 3M Open on his third professional start.
