Alexander Zverev has won just two of his 10 career meetings against Dominic Thiem.
But when the two meet Saturday in the Mutua Madrid Open semifinals, he will be the slight favorite.
The lingering memory of this rivalry is from the last time they met, in the 2020 US Open men’s singles final.
Zverev had every opportunity to win his first major title. Somehow, he lost and Thiem was the one who won his first.
They meet again on the clay, on the same court they played on the last time Zverev got the better of the Austrian in 2018.
