Kyrgios is a genius says Judy Murray after he serves underarm in Miami win


Kyrgios will play Croatia’s Borna Coric in the last 16 in Miami

Controversial Australian Nick Kyrgios has been called a “genius” by former British Fed Cup captain Judy Murray, who is “surprised” no other players follow his lead.

It comes after world number 33 Kyrgios, 23, twice served underarm during his 6-3 6-1 defeat of Serb Dusan Lajovic at the Miami Open on Monday.

A spectator was ejected after a mid-match argument with Kyrgios.

“The underarm serve,” Murray wrote on Twitter
