German fourth seed, Alexander Zverev, will face 14th seeded American, John Isner, in the final of the Miami Masters tennis tournament.

Zverev defeated Spaniard Pablo Carreno Busta in the semi-final, while Isner upset fifth seed, Juan Martin Del Potro of Argentina.

Twenty-year-old Zverev is aiming for his seventh ATP career title. And in the absence of top seeds, Roger Federer and Marin Cilic, the German should fancy his chances.

Zverev produced a fine performance throughout and recorded an impressive 7-6, 6-2 win in 88 minutes to book his place in the final against big-serving Isner.

“He is playing the best tennis of his life so it is going to be great. I am looking forward to it. I am actually quite happy that he is in the final. He is somebody that I grew up with. On the practice courts he has been practicing with me since I was 14 years old. I was lucky as a junior to have him at the Saddlebrook Academy, and it is going to be a great final,” says Zerev.

Earlier, Isner played great tennis to end Del Potro’s 15-match winning streak. Del Potro was visibly tired and Isner dominated the first set, quickly bagging it 6-1.

Del Potro provided more resistance in the second but Isner’s serve and high-quality all-round play proved too much.

Del Potro eventually ran out of steam as Isner recorded a 6-1, 7-6 victory.
