Dominic Thiem crushes Alexander Zverev to book semi-final spot

Austrian Dominic Thiem destroyed a lacklustre and battle-weary Alexander Zverev 6-4 6-2 6-1 on Tuesday to reach the French Open semi-finals for the third consecutive year.

Claycourt specialist Thiem's relentless accuracy from the baseline proved too much for second seed Zverev who looked jaded after a gruelling path to his first Grand Slam quarter-final.

After an even start full of high quality ball-striking, Thiem broke serve at 3-3 and quickly got on top, stretching his opponent all over Court Philippe Chatrier.

Second seed Zverev, 21, needed his left thigh strapped in the second set and looked disconsolate as Thiem widened his advantage with a clinical display of hitting.

Thiem, seeded seventh, needed only 15 minutes to go 4-0 up in the third with Zverev barely running for wide balls.

Zverev began to let rip, snatching one game back, but the outcome was inevitable and Thiem put him out of his misery with a routine backhand winner into a wide-open court.

Thiem will face either former champion Novak Djokovic or unseeded Italian Marco Cecchinato in the last four.
