World number four Alexander Zverev beat Spaniard Carlos Alcaraz, and Frances Tiafoe will meet him in the final after defeating Jannik Sinner.
World number four Zverev needed just over an hour to beat the young Spaniard, who had got past Brits Daniel Evans and Andy Murray earlier in the week.
The match went with serve until the seventh game of the first set, when Zverev set up two break points and converted the second of them.
