MALAGA, Spain — Italy returned to the Davis Cup final after a gap of 25 years as Jannik Sinner beats Novak Djokovic in both singles and doubles to secure a 2-1 victory over Serbia on Saturday that earned the 1976 champions a title clash with Australia.

Mr. Sinner and doubles partner Lorenzo Sonego beat the Serbian duo of Djokovic and Miomir Kecmanovic6-3 6-4 to secure a famous victory that sent the former champions packing and sparked wild celebrations at a heaving Martin Carpena Arena in Spain. Up next for Filippo Volandri’s side, who will be playing in an eighth final and seeking a second trophy, are 28-times champions Australia after Lleyton Hewitt’s team eased past giant-killers Finland on Friday.

Mr. Sinner earlier saved three matchpoints to stun Djokovic 6-2 2-6 7-5 in an extraordinary singles match to help Italy draw level with Serbia at 1-1 after Kecmanovic had put the 2010 champions ahead by beating Lorenzo Musetti 6-7(7) 6-2 6-1.

Mr. Sinner was facing Djokovic for the third time in 11 days and the world number four, who beat the top-ranked Serbian early in the ATP Finals before losing to him in the title clash, made a quick start to ease through the opening set with two breaks. — Reuters
