Day 10 of the Australian Open saw the enduring class of Rodger Federer get the better of Tomas Berdych, whilst young pretender Hyeon Chung will meet the Swiss superstar in the semi-final after defeating Tennys Sandgren. As ever, we have rounded up all the action and talking points from Melbourne Park in our daily review.
Defending champion Roger Federer swept into a record 14th Australian Open semi-final with a commanding straight sets win over rival Tomas Berdych. The second seed cruised to a 7-6 (7/1), 6-3, 6-4 win in 2hr 14min on Rod Laver Arena. The 19-time Grand Slam champion, who hasn't lost in five matches against Berdych in Melbourne, will play in his 43rd Grand Slam semi-final, a record for the post-1968 Open Era.
Federer's latest victory was his 92nd in 105 matches in Melbourne to make the Australian Open his most successful Grand Slam in terms of matches won.
Up next for the Swiss legend is 21-year old South Korean Hyeon Chung who continued his historic run at the Australian Open with a 6-4 7-6 (7-5) 6-3 win over American Tennys Sandgren in the quarter-finals. A rising star on the ATP World Tour, Chung has beaten Novak Djokovic & No.4 Alexander Zverev on route to the last four and will be eyeing the scalp of one of the all-time greats to progress to the final.
German Angelique Kerber brushed past Madison Keys at the Australian Open, reaching her sixth grand slam semi-final in style. The German two-time major winner capitalised on an error-filled display by Keys, racing to a 6-1 6-2 victory in just 51 minutes.
Keys, playing in her fourth grand slam quarter-final, made too many mistakes, her 25 unforced errors proving costly. The form player in the women's draw, Kerber is yet to lose in 2018, having won the Sydney International title ahead of the year's first major.
Kerber will now take on number one seed Simona Halep for a place in the Australian Open final. The Romanian produced a dominant display to ease past Karolina Pliskova in the Australian Open quarter-finals on Wednesday. The world number one was in impressive form on Rod Laver Arena, needing just 71 minutes to beat Pliskova 6-3 6-2 and move into her first semi-final at Melbourne Park.
