Carlos Alcaraz won the Cincinnati Open title in anticlimactic circumstances as rival Jannik Sinner retired due to illness just 23 minutes into the match.

CINCINNATI — Carlos Alcaraz won the ATP Cincinnati Open title on Monday after defending champion Jannik Sinner retired due to illness in the first set. World No 1 Sinner came into the final feeling unwell and lost the first seven points of the match, before throwing in the towel at 5-0 down in a game played in 30 C heat.

Carlos Alcaraz will do everything he can to overtake his top rival Jannik Sinner and return to the top of the ATP rankings by the end of this season, which is why he is also giving his best at the Cincinnati Masters 1000 which precedes the US Open (scheduled in New York from August 24 to September 7).
