SAINT-QUENTIN-EN-YVELINES, France — An Olympic medal will go a long way for South Korean golfers Tom Kim and Byeong Hun An. At stake this week at Le Golf National is a chance to avoid mandatory military service. It's a topic that comes up for South Koreans at every Olympics since golf returned to the program in 2016. And it's a topic the 22-year-old Kim is trying to avoid. He has said his only focus is to win a medal for South Korea. But it's starting to come into view. Kim is three shots out of the lead going into the weekend.
