Roger Federer had an unexpectedly easy passage through to a 30th grand slam final when Chung Hyeon retired during the second set of their semi-final in Melbourne.

The 21-year-old Korean, playing in his first slam semi-final, had been struggling with a blister for several days and, at 6-1 5-2 decided he could no longer continue, sending Federer through to a clash with Marin Cilic.

Young Scot Aidan McHugh’s bid for a first junior grand slam title ended when he was beaten in the semi-finals of the boys’ singles.

In the jungle

Bernard Tomic was keen to remind everyone again how much money he’s earned from tennis after falling in qualifying at the Australian Open but it seems he has been lured by the call of the jungle. Rumours have been around for a while that Tomic is to be one of the contestants on the Australian version of I’m a Celebrity… Get Me Out of Here, and those appear to have been confirmed. The show’s Twitter feed put out a teaser with an anagram of the tennis star on the series, which unscrambles to ‘Wimbledon quarter-finalist’. Tomic reached the last eight in 2011.

Kristina Mladenovic is on an almost unbelievable 15-match losing streak in singles dating back to last August but the Frenchwoman leaves Australia as a grand slam champion after winning the women’s doubles with Hungary’s Timea Babos. She hopes it can help her end her singles slump, saying: “It’s a grand slam title that I add to my career. It’s so emotional. It’s great. When you live a moment like this, there is no reason why it couldn’t work in singles. Obviously it’s a lot of confidence, just positivity for me.”

Saturday highlights

Simona Halep and Caroline Wozniacki will do battle in a grand slam final with plenty at stake. Both are bidding for their first slam title after previously losing in two finals – Halep at the French Open and Wozniacki twice at the US Open, while the winner will leave Australia as world number one. The men’s doubles title will also be decided, with in-form Oliver Marach and Mate Pavic facing Juan Sebastian Cabal and Robert Farah, along with the girls’ and boys’ singles crowns.
