Rune's mother explains her son's defeat in Rotterdam: "He had to stay in bed all day".

Holger Rune was beaten in two sets yesterday by Pedro Martinez, a player far from a specialist in indoor conditions.

After the Dane's unexpected defeat, his mother Aneke spoke to Danish media outlet TV2: "He caught the flu in Denmark after the Davis Cup, and he wasn't feeling well in the match against Sonego.

He had a high fever and we had to consult a doctor. After that, he stayed in bed all day."

For his part, Rune admitted that he had had a "very bad night" before his match, which explains the level displayed by the world No. 12 on Rotterdam's center court yesterday.
