Yes, Zarathustra, I think you may be right. Dupuis was a couple of weeks shy of his 31st birthday when he won his first title earlier this year. I think he has the record. I thought perhaps it was the Moroccan Vowel Man, but he won his first at 28, or so. These "old" guys can still play, huh? Agassi's turns 34, next month and can still win occasionally, but won his first title as a teenager back in the 1950's.
Okay, here's a good trivia question.......who was the last guy to win an ATP Tour singles title using a wood racquet? Maybe someone will know......I don't.
