Zverev, who settled a court case in Germany two days ago over domestic abuse allegations, came into the Roland Garros final on a 12-match winning streak after collecting the title in Rome last month.

His calf muscles and thighs hit by cramp, Flavio Cobolli’s body could no longer respond in the fifth set of the French Open final.

Zverev, 29, secured his first Grand Slam title after three previous final defeats, triumphing 6-1, 4-6, 6-4, 6-7 (5), 6-1 in four hours, 16 minutes.
