Alcaraz Heartbroken After Withdrawing From Davis Cup Finals. Carlos Alcaraz announces he is “heartbroken” as he pulls out of Spain’s Davis Cup Finals team due to injury. The world number one is advised to rest after swelling is detected in his right hamstring. Alcaraz had just competed at the ATP Finals, where he was defeated by Jannik Sinner in the final. Spain is set to face the Czech Republic in the Davis Cup quarter-finals in Bologna on Thursday. The 22-year-old, who claimed both the French Open and US Open titles this year, says playing for Spain is “the greatest thing there is.” Medical tests reveal a significant muscle strain with marked oedema after he experienced discomfort in the final against Sinner. Italy will also be without world number two Jannik Sinner and Lorenzo Musetti, leaving Alexander Zverev as the only top-10 player in the eight-team event. Alcaraz recently secured the year-end world number one ranking after three straight wins in the ATP Finals’ group stage.
