Andy Murray beats Stefanos Tsitsipas to reach Boss Open semi-finals

Andy Murray beat a top five player for the first time in two years as he advanced to the semi-finals of the Boss Open.

The Greek top seed was beaten by the British.

One of the biggest victories of Murray's career was achieved on the grass court, where he ranked in the top 10.

His last win over a top five player was against Novak Djokovic.

Murray will play in the semifinals.

When the Hungarian retired with an injury, Australia's Kyrgios was leading by three.

Murray is ranked 68th in the world and has entered a number of grass-court tournaments to prepare for Wimbledon, where he will attempt to win the title for the first time.

Murray saved a set point in the opener and then broke for a 4-3 lead in the tie-break.

Four of the last five games were won by the three-time Grand Slam champion.

"Maybe this surface suits my style, but I don't want to say I was the smarter player."

"Stefanos plays well on all surfaces but this works well for my game and I use my strengths better."

At the start of the year, Murray reached the final of the Sydney Tennis Classic but has not won a singles title on the tour.
