Knowing that they're not likely to get them back once they've become the Big Thing, Tennis Auckland concentrates much of its recruitment drive on finding the Next Big Thing.
Roger Federer and Rafael Nadal have passed by on their way to glory and recruiter Jeff Simpson is full of hope that Ryan Harrison might one day have a similar impact on the world game.
That's why the 19-year-old American, one of only two players under 20 ranked inside the world's top 100, has been granted the Heineken Open's first wildcard. It might not please a few local players, but there's always qualifying.
Long-time Davis Cup captain Simpson said after a long time in the doldrums, Harrison and Donald Young, ranked 39 in the world and also coming to Auckland, represents an opportunity for US men's tennis to reclaim lost ground.
"We always look to pick out a couple of up-and-comers," Simpson said. "Ryan is an interesting young man. He just started on the circuit a few years ago - he was 15 when he played his first Futures tournament in Mexico - and he progressed really quickly."
