Nick Kyrgios scripted his third major victory of the week on Friday when he defeated John Isner 7-5 5-7 7-6(7) to set up a showdown against Alexander Zverev in the final of the Acapulco International in Mexico.
The 23-year-old Australian followed victories over multiple grand slam winners Stan Wawrinka and Rafa Nadal with a hard-fought win over Isner, the American who sits 63 places above him in the world rankings.
Of the victory, Kyrgios said: "It was an amazing, fun match with John today. I was pretty pumped because I knew there wasn’t going to be a lot of running.
"He’s a good mate of mine and has always been incredibly supportive. To go out and battle against him was a special moment for me.”
Break points and chances were few and far between in sultry conditions on Mexico's Pacific coast with each player struggling to find that little bit extra.
Isner won more points on serve and return overall but the temperamental Aussie came through when it mattered, particularly in the third set tiebreak, which he finished with a masterful drop shot from the base line.
