Originally I thought the question was what Welshman made his debut for TT. So I gave up.
So much for my comprehension skills.
Jason Brown: May 27, 2006.
Gareth Bale: May 2006 - age 16 and 315 days. Wale's youngest international ever.
David Cotteril - same date as above.
Glynn Garner - same date.
Wales won 2-1 in Austria.
Tall Man, that's four, not three.
