Diego Sebastián Schwartzman (Spanish pronunciation: [ˈdjeɣo seβasˈtjan ˈʃwaɾtsman], German: [ˈʃvaʁtsman]; born 16 August 1992) is an Argentine former professional tennis player. He won four ATP Tour singles titles and reached his career-high singles ranking of world No. 8 in October 2020. As a clay court specialist, his best results were on this surface. He was noted for his high-quality return game. When he reached the quarterfinals of the 2017 US Open, the 170-centimetre (5 ft 7 in) Schwartzman was the shortest major quarterfinalist since the equally-tall Jaime Yzaga at the 1994 US Open.
