Yahoo Sports reports: Having spent a large part of the night vomiting and deprived of sleep, Matteo Arnaldi was in no shape to fight for a spot in the French Open final. The 104th-ranked Arnaldi withdrew before the first all-Italian men's Grand Slam semifinal against Flavio Cobolli on Friday at Roland Garros. Arnaldi believed he caught a virus and said he could not play competitive tennis.
