In a stunning victory, South Korea's first tennis player to reach the quarters of a Grand Slam, Hyeon Chung stormed into the Semi finals of Australian Open after beating Tennys Sandgren.

Now, Hyeon Chung will play either the redoubtable Roger Federer or the big serving Tomas Berdych. Interestingly, the South Korean player is ranked 58th in the world. He became a giant-killing sensation at the Australian open after knocking over one of the favourites for the trophy-Novak Djokovic, the Serb legend. The electrifying match between Chung-Djokovic made tennis lovers sit up and take notice of the rising South Korean star.

Now, fans await the the Federer-Chung which would well turn out of be another edge-of-the-seat thriller unless of course he ends up facing Berdych which will be another match to watch out for.
