American Marconi Wireless News - Sinner in Rotterdam semi-finals as injury-plagued Raonic quits

Top seed Sinner took the first set 7-6 (7/4) before the big-hitting 33-year-old Canadian called it quits after two more games.

Sinner goes on to face Dutchman Tallon Griekspoor, who defeated Emil Ruusuvuori of Finland, 7-5, 7-6 (7/4) for a place in Sunday's final.

"Obviously this is not the way you want to win the match," said Sinner.

"I wish him a speedy recovery. I was actually playing and I was not realising that he was about to retire but he knows his body really well and he knows his limits so, for sure, it's the right choice for him."

Sinner, 22, can take the world number three ranking if he wins the title on Sunday. If that happens, he would become the highest-ever ranked Italian man.

Raonic saw two set points come and go in the opener on Friday before he retired as the 2016 Wimbledon runner-up endured another injury nightmare.

The former world number three has slumped to 309 in the rankings after missing two years of action due to a combination of back, ankle and knee injuries.

Earlier Friday, Bulgarian sixth-seed Grigor Dimitrov edged into the semi-finals, seeing off a determined challenge from Kazakhstan's Alexander Shevchenko 7-6 (7/2), 3-6, 6-4.

Dimitrov will next face fifth seed Alex De Minaur after the Australian shocked second seed Andrey Rublev 7-6 (7/5), 4-6, 6-3.

World number 13 Dimitrov seemed unhappy with his performance, admitting he struggled to read the Shevchenko service.

"The way he was serving was just incredible. For some reason I was not really able to find my angles. He was not giving me any time to develop my game," Dimitrov said.

"Today was just one of those matches because I was not at my best. Hopefully I can raise my game" for Saturday's semi-final.

Dimitrov defeated De Minaur in the last-eight in 2023.

The Australian will be hoping to avenge that loss on Saturday when he also celebrates his 25th birthday.

"I played him on my birthday last year, and he was rude enough to beat me when I was two match points up," said De Minaur.

"I'm playing him tomorrow, which will be my birthday again, so I'm hoping he's a little bit nicer to me. We'll see."
