Madison finds the Keys and coach Murray impresses – what we learned in Melbourne

Jannik Sinner and Madison Keys are leaving Melbourne with added baggage after being crowned Australian Open champions.

Sinner successfully defended his title and tightened his stranglehold on men’s tennis, while Keys finally fulfilled her teenage promise a month before her 30th birthday.

Here, the PA news agency picks out five things we learned from the year’s first grand slam.

It’s never too late

At 14, Keys seemed destined to be a grand slam champion. At 24, the dream was still very much alive. But, at 29, the American had learned to be at peace with the fact it may never happen. And then it did. Keys not only won the title, she did it by playing brave, first-strike tennis and beating both Iga Swiatek and Aryna Sabalenka in matches that went to the wire. Her success should be a shot in the arm for other players who feel their chance has passed.

Murray finds a new role

Mixed fortunes for Brits

Djokovic feeling his age

Djokovic’s victory over Carlos Alcaraz in the quarter-finals was one of the matches of the tournament and proof that the 37-year-old’s tennis is still more than good enough to win best-of-five-set clashes with his biggest rivals. But the physical aspect is just as important and even Djokovic cannot hold back time. Two years ago, he managed to win the tournament despite a hamstring tear. This time, the pain was too great. The Serbian has openly said he only cares about the grand slams and Davis Cup now, but can his body still cope with seven full-length matches against rivals 15 years his junior? Wimbledon appears his best bet of that record-breaking 25th slam title.

The kids are coming

Move over Sinner and Alcaraz, there’s a new next gen. The Italian and the Spaniard will almost certainly rack up plenty more slam titles, but the teenagers coming through are likely to have a big say in men’s tennis over the next few years. Brazil’s Joao Fonseca – only 18 but with a huge game – is the most talked-about talent and he stunned Andrey Rublev, but Czech Jakub Mensik and American Learner Tien, both 19, went further in the tournament. There will be four teenagers in the ATP top 100 on Monday compared to just one in the women’s game.
