Rafael Nadal ended up slaying Nick Kyrgios in an epic Wimbledon second round match, at Centre Court. In what turned out to be a hotly-contested affair, the latter did surprise the crowd with a mixed bag of tricks, but also was accused of unsportsmanlike behaviour. At one point, the crowd including the Spaniard were taken aback by an underarm serve by the Australian.
The current world number two edged past his younger opponent, in four sets 6-3 3-6 7-6 (7/5) 7-6 (7/3).
In the past, Nadal had also criticised Kyrgios' attitude, stating that the latter lacks respect towards opponents and himself.
Kyrgios also received a warning for unsportsmanlike behaviour after an argument with the umpire. It due to twice serving under-arm.
