Jannik Sinner retires with cramp to give Griekspoor victory at Shanghai Masters

Jannik Sinner had to retire from his match against Tallon Griekspoor at the Shanghai Masters due to cramps caused by the intense heat and humidity. This is disappointing for Sinner, especially as he was competing in the final stretch of a challenging season. His withdrawal not only affects his chances in the tournament but also highlights the physical toll that extreme weather can take on athletes. Meanwhile, Amanda Anisimova's victory at the China Open adds a contrasting note of success in the tennis world.
