Alexander Zverev defeated Kei Nishikori in straight sets on Saturday to reach the final of the Washington Open.
The 20-year-old German took just 63 minutes to defeat his Japanese opponent 6-3, 6-4 and make his eight career final and fifth in 2017.
It was the first meeting between the two, but Zverev dominated, breaking Nishikori in the second games before serving out for the set.
A single break in the third game second set was enough for Zverev, who was never threatened on his serve, winning 31 of 33 points on his first serve.
Complete and clinical performance from Alez Zverev.

Earlier in the day, big-serving South African Kevin Anderson made the final after a comfortable 6-3, 6-4 win over American Jack Sock.
Anderson fired down 12 aces while saving five break points against Sock to reach his first ATP World Tour Final for almost two years.
He got off to a great start, breaking Sock in his first service game and holding serve to take the first set in just over half an hour.
He then fought off three break points with aces as he claimed the second set and the victory.

“It feels great. It’s great to get another match win today. It was definitely a tough match,” said world number 45 Anderson.
“I felt I did quite a few things well today, couple things I thought I could have done a little bit better. But most importantly I was able to get the win and give myself a shot at the title tomorrow.”
