Second-seeded Daniil Medvedev has lost in the first round of the French Open in five sets to an opponent who is ranked just 172nd and was playing only his second match in the main draw of any Grand Slam tournament. Thiago Seybolt Wild is a 23-year-old from Brazil who needed to go through qualifying rounds at Roland Garros just to earn a spot in the men’s bracket. He looked very much like he belonged on Court Philippe Chatrier on Tuesday. He hit big forehands and kept his nerve down the stretch to win 7-6 (5), 6-7 (8), 2-6, 6-3, 6-4.
