Denmark's Holger Rune fought back from a match point down to reach the Japan Open semifinals after beating Kei Nishikori 3-6, 6-2, 7-5 on Sunday.

Rune, the No. 6 six seed, came back from the brink to win four straight games and end the Japanese veteran's challenge in front of a lively crowd in Tokyo.

"It was about getting that first serve, and if I could save that match point I knew that I could put on pressure," Rune said.
