Italy's Davis Cup hero Jannik Sinner said it was a "special feeling" to end his team's 47-year drought in the competition on Sunday in Malaga.

Italy won the Davis Cup for the first time since 1976 as Jannik Sinner crushed Alex de Minaur 6-3, 6-0 to seal a 2-0 win over Australia on Sunday in Malaga.

Novak Djokovic said he accepts responsibility for Serbia's Davis Cup semi-final defeat by Italy on Saturday after failing to convert three match points against Jannik Sinner.

A "proud" Jannik Sinner beat world number one Novak Djokovic twice in one day to send Italy into the Davis Cup final with a 2-1 win over Serbia on Saturday in Malaga.

Alex de Minaur guided Australia into a second successive Davis Cup final with an assured 2-0 win over Finland on Friday in Malaga.

Novak Djokovic closed in on a record-breaking seventh ATP Finals title on Saturday after sweeping past Carlos Alcaraz 6-3, 6-2 in a dominating semi-final display he hailed as his best of the tournament.

World number one Novak Djokovic beat ATP Finals alternate Hubert Hurkacz 7-6(1) 4-6 6-1 in their Green Group clash on Thursday and advanced to the semi-finals after Jannik Sinner edged Holger Rune 6-2 5-7 6-4 in the evening match.

Russian Zverev put on a powerful display to see off world number two.

The 24-time Grand Slam champion needed just one win or a defeat for young rival Carlos Alcaraz in order to secure top spot in the ATP rankings for 2023 and prevailed in a three-hour Green Group clash with spirited debutant Rune.

The 36-year-old Djokovic eclipsed his previous record set two years ago as the tournament's oldest champion, capturing his 40th Masters 1000 title and stretching his winning run to 18 matches.
