Serena Williams bows out in Cincinnati as Emma Raducanu shows no mercy

• British No 1 breezes to 6-4, 6-0 win in first-round encounter
• Retiring American has won just once in last three tournaments

Even in the face of all-time greatness and unprecedented longevity that has spanned 27 remarkable years, time is undefeated and it will eventually come for us all. With every passing day, the end of Serena Williams' professional tennis career draws alarmingly near and the chances of one final, spectacular result fades.

In what is likely the penultimate tournament of her great career, Williams bowed out of the Western and Southern Open in her opening round match with a grim performance, emphatically losing 6-4, 6-0 to a spotless Emma Raducanu who did not put a foot wrong throughout.
