On Monday, Casper Ruud rolled over Carlos Alcaraz in the first round of the ATP Finals. After losing in straight sets to Ruud, Alcaraz gave three excuses for his poor play. One of the most important reasons was his health.

TURIN, Italy, Nov 11 (Reuters) - An off-colour Carlos Alcaraz suffered a shock 6-1 7-5 defeat against Norway's Casper Ruud in his opening match at the ATP Finals as the Spaniard's hopes of winning the year-end title for the first time suffered a blow on Monday.

Casper Ruud’s first victory over Alcaraz in 5 career meetings could make it difficult for the Spaniard with Germany’s Zverev on a hot streak.
