John Isner continues to shine in Atlanta but Nick Kyrgios booed off

John Isner celebrates

John Isner has progressed into the semi-finals of the Atlanta Open after defeating Mischa Zverev.

The American is seeking his fifth Atlanta title on the ATP Tour, and was rarely troubled by German Zverev, despite losing the middle set.

“He is a tough player. I played well today. I needed to,” Isner said following the 7-5 4-6 6-1 win.

“It was a weird match. The balls were bouncing everywhere, it was tough to control. I was happy to get through in three sets.”

Isner will face Matthew Ebden for a place in the final after the Australian defeated Marcos Baghdatis 6-3 6-2.

The other semi-final will see Ryan Harrison take on Cameron Norrie after he advanced past an injured Nick Kygrios.

The Australian lost the first set and was trailing 0-3 int the second when he decuided he could not continue due to a hip injury, much to the disdain of the Atlanta crowd.
