British talent Jack Draper has reached the semi-finals of the Adelaide tennis tournament. Draper, the first opponent of Spaniard Rafael Nadal at the Australian Open next week, surprised the Russian number 3 on the seeding list Karen Chatsjanov: 6-4 7-6 (3). Last week, the Russian in the same place, in the first of two preparatory tournaments, was still too strong for the 21-year-old Briton.
