Auckland-raised Cameron Norrie will meet American Tennys Sandgren in the ASB Classic final after defeating German Jan-Lennard Struff 7-5 4-6 6-3 in the semi.
Fighting to qualify for his first ever career ATP Tour final, Norrie may have found his feet early in the match but Struff proved a tough competitor.
Norrie's signature backhand and sweeping shots kept the scoreboard ticking over, but it wasn't long before bullet serves of at least 214km/h had Struff gaining momentum.
Both players notched two break points apiece, but Norrie edged in front 7-5 to take the first set.
In the place he used to call home, the 23-year-old had earlier said he could feel the support of the Auckland crowd building but it wasn't enough in the second stanza.
Running on fumes after qualifying for both the singles and doubles semi-finals, Struff knew he had to turn it up or risk forfeiting the chance of a debut finals appearance, going on to take the set 6-4 and send the match to a deciding third set.
Battling through sweltering 43C temperatures on court, it was Norrie who made the early break with a 3-0 lead, pushing on to win 6-3.
Wildcard Norrie will meet Tennys Sandgren in tomorrow's final after the American defeated German Philipp Kohlschreiber in straight sets 6-4 6-2 in round one of play.
New Zealand's number one tennis player Michael Venus and South African partner Raven Klaasen are also vying for a finals spot when they meet American duo Bob and Mike Bryan in the doubles semi-final later tonight.
