TENNIS Djokovic, Federer to meet for 50th time

Defending champion Novak Djokovic on Tuesday overcame the powerful serve of Canada's Milos Raonic, defeating him 6-4, 6-3, 7-6 (7-1), to set up an Australian Open semifinal clash with Roger Federer, their 50th career matchup.

Earlier, Federer pulled off the second great escape of his Melbourne campaign by saving seven match points to win 6-3, 2-6, 2-6, 7-6 (108), 6-3 against unseeded Tennys Sandgren en route to a record 15th semifinal appearance in the slam.

On the women's side, Wimbledon champion Simona Halep needed only 53 minutes to beat Anett Kontaveit 6-1, 6-1 and seal a place in the Australian Open semifinals for the second time in three years. The No. 28-seeded Kontaveit held the opening game at love, but the 28-year-old Romanian was relentless in an 11-game winning streak that took the match away from her Estonian rival.
