LONDON: Italy’s Matteo Berrettini served notice of his intention to mount another strong challenge at Wimbledon after joining an elite group of players by retaining his ATP Queen’s Club title on Sunday. Berrettini defeated Serbia’s Filip Krajinovic 7-5, 6-4 in the final of the Wimbledon warm-up event. He will now be aiming to go one better at Wimbledon, the only one of tennis’s four majors still played on grass, after losing to Novak Djokovic in last year’s final Berrettini’s victory meant he joined John McEnroe, Jimmy Connors, Boris Becker, Ivan Lendl, Lleyton Hewitt, Andy Roddick and Andy Murray as the only players in the Open era to win back-to-back Queen’s titles. The world number 10 has been in superb grass-court form this season following a return from hand surgery. Berrettini, 26, has now won two tournaments in a row, after beating Murray in Stuttgart last weekend, and Sunday’s success was a further boost to his confidence just eight days before the start of Wimbledon.
