he 21-year-old third seed was clinical as he trounced erratic Canadian Shapovalov, two years his junior, 6-4 6-1 in less than an hour on centre court.
Earlier in the day, Thiem backed up his shock defeat of defending champion Rafael Nadal in the quarter-finals to beat South Africa’s Kevin Anderson 6-4 6-2 and reach the final for the second year in succession.
Zverev and Shapovalov did not take to court until around 10 pm local time after Petra Kvitova's marathon final victory over Kiki Bertens in the women’s singles.
Initially, it appeared the eagerly-anticipated clash between two dynamic shotmakers, who are expected to be battling for grand slams in the near future, would live up to the pre-match billing.
The opening eight games went with serve with Shapovalov producing some trademark backhands winners from his single-hander, including one audacious topspin lob.
Zverev already has two Masters 1000 titles to his name, and his greater experience told in the ninth game.
Shapovalov framed a forehand at 30-30 to offer the first break point of the match and Zverev pounced with a crunching backhand return his opponent fended into the net.
The second set proved a no-contest as Zverev took complete control against a dispirited looking opponent.COMMANDING DISPLAY

Thiem claimed a first win against Anderson at the seventh attempt with a commanding display.
None of their previous meetings had been on Thiem’s favoured clay and the surface proved decisive as he managed to dictate against Anderson who was appearing in his first semi-final of a Masters 1000 event.
Thiem needed a single break of serve in the opening set and broke twice in the second to wrap up the victory.
He said his victory over Nadal had been a timely boost after being thrashed by the Spaniard in Monte Carlo and falling in the quarter-finals in Barcelona.
“It gave me a huge boost of confidence,” he said. “That’s for sure. But at the same time, it was a completely different matchup today.
“There was also the fact that I never beat him. It was 0-6 before today. Some things were a little bit shaky. But I was keeping my level up from yesterday, so that was a great thing.”
Thiem will need to maintain his level if he is to claim a first Masters 1000 title on Sunday although he does boast a 4-1 career head-to-head lead over Zverev.
