Kohlschreiber's record in Auckland is exemplary. The second of his four career titles came here in 2008 when he downed Juan Carlos Ferrero in the final. Today's semifinal against big-serving American Sam Querrey - also a finalist here in 2009 - will be Kohlschreiber's fourth in Auckland. In nine visits he has failed to reach the quarter-finals just once.
It's that type of consistency that has kept Kohlschreiber inside the top 50 since 2008. Last year was his best on tour yet. He reached a first career Grand Slam quarter-final at Wimbledon and picked up a title on clay in Munich, his second success in that event.
At 29, he's "for sure wiser, and older, yes". He's happier about the first part of that equation than the second.
"Sometimes it is good. I understand tennis a little bit better, have a different perspective, but sometimes it would be great to be 22 again."
Not that age is wearying him yet. An aesthetically pleasing strokemaker with a one-handed backhand - "the response I get from people is that I have a beautiful backhand, so that's nice", he said last year - Kohlschreiber doesn't have the weapons to overpower many opponents. Instead he relies on precision and relentless pressure.
"I am a fighter on the court," he said. "I like to play with a lot of intensity, to put pressure on my opponent."
So far, so good in 2013, a year in which he wants to stay inside the top 20, and maybe pinch another title. He won his first match of the year in Doha before dipping out to Gael Monfils in the second round in Qatar.
In Auckland, he battled past Colombian Alejandro Falla in three sets, before yesterday accountingfor Xavier Malisse in straightsets.
It looks as though he's getting better with every outing. And, so far, he's even managed to hold the attention of most of the crowd.
