Input: Question: Which player won the championship that Nakano reached the fourth round in in 1938? Passage:Nakano reached the fourth round of the men's singles at the 1938 French Championships, a feat that would not be achieved again by a Japanese man until 2013. In July he was eliminated in the semifinals of the Queen's Club Championships by eventual winner Don Budge. In the fourth round he lost in three straight sets to Frantisek Cejnar from Czechoslovakia. In September of the same year he also reached the fourth round of the U.S National Championships in which he was defeated in four sets by Bobby Riggs. Together with his countryman Jiro Yamagishi he reached the quarterfinal of the men's doubles at the 1937 Wimbledon Championships. The two won the Maidstone Club's invitational tournament later the same month. They also clinched the doubles title of the Pacific Coast Men's Doubles Championship at the La Jolla Beach and Tennis Club. In August he reached the quarterfinal of the Newport Casino Invitational falling to Frank Parker. As a result, he became the third ranked player of Japan that year.
