Advancing age does nothing to dampen the fighting spirit of German third seed.
He's had three shoulder operations, hip surgery and an elbow operation. His nerves have been pinched by epidural injections, and he has waged war on atrophied muscles, knowing that they'll never be quite the same no matter how much gym time he puts in.
He stares at the ceiling in hotel rooms wondering why he isn't at home with his 2-year-old daughter. And yet, at 34, Tommy Haas is still out on tour, still playing so well he is the third seed at this week's Heineken Open.
Haas has defied time. Heading into last year the German - whose career topped out with four Grand Slam semifinals and an Olympic silver medal - looked gone after injuries and inactivity saw him slide outside the top 200. But he bounced back with a storming campaign, surging back to 21 in the world and achieving his goal of winning a 13th career title.
He did so in fine style, besting Roger Federer on grass in the final at Halle. It's the feeling he gets from glory days like that in the small east German salt-harvesting town that keeps him coming back long after the gathering of over US$11 million in prizemoney obliterated the financial necessity to do so.
