John Isner ends Juan Martin del Potro’s quest for Sunshine Double

John Isner celebrates

Juan Martin del Potro’s hopes of achieving the Sunshine Double have been dashed by a semi-final defeat to John Isner.

The Argentinian has been in tremendous form of late, and defeated Roger Federer to win at Indian Wells earlier this month.

He was widely tipped to follow that up with success in Miami too, but it’s American Isner who now has the chance to lift the trophy following his 6-1 7-6 (7/2) semi-final win.

The 32-year-old broke Del Potro twice in the first set, which he took in 27 minutes, while the second went to serve forcing a tiebreak.

Isner will face Alexander Zverev in the final after the German made short work of Pablo Carreno Busta in the other semi-final.

After a first set which followed serve, Zverev immediately lost serve as Carreno Busta took the advantage, but the German held strong winning the last three points, two against serve, to take the set.

The second was a shorter affair, the world number five breaking for 2-1 and 5-2 before serving to love for the match.
