A focused Nick Kyrgios overcame a hand injury, leg cramps and a strong performance from Stan Wawrinka to prevail 7-5 6-7(3) 6-4 and advance to the semi-finals of the Acapulco International. The mercurial Australian, who defeated Rafa Nadal the night before in a match where the Spaniard later criticized Kyrgios’ on-court demeanor, outplayed Wawrinka in the match’s biggest moments despite playing in front of spectators who vocally backed the Swiss. “I actually play better when the crowd is against me and giving me a bit of stink,” the 23-year-old said. “I love it. It gets me going.” The night did not begin well for the hard-hitting Kyrgios, who slipped while thumping a backhand in the first game, opening up a cut on his right hand that required medical attention.
